Speed and Love Chinese Drama – Full Cast, Plot Summary, Episodes, OST & Ending Explained

There are C-dramas you enjoy. Then there are the ones that get under your skin. Speed and Love (双轨) is the second kind.

Picture this: a girl who grew up sheltered and studious, writing letters that never got a reply for ten years — flying alone to Thailand at nineteen to find a boy she refuses to forget. When she finally finds him, he’s not the gentle big brother she remembers. He’s a street racer. An underground boxer. Someone who built walls around himself so high that getting close means risking everything.

That gap — between who they were and who they became — is where Speed and Love lives. And it does not let you go easily.

This is the full breakdown: cast, story, ending explained, episode guide, where to stream, and everything in between.

Speed and Love landed as one of the most-watched Chinese action romance dramas of late 2025, ranking in the top 600 all-time on MyDramaList with over 35,000 watchers logged. For a drama that flew somewhat under international radar before its premiere, the audience response after release was anything but quiet.

Genre, Director & Production Company

Speed and Love is an action romance drama directed by Yu Zhongzhong and Zhao Xiaolei, with Zhao Xiaolei also credited as screenwriter. The production is an iQIYI original, part of the platform’s 2025 premium drama slate. The series combines the visceral energy of underground racing and boxing with an emotionally slow-burn romance — a combination that sounds unlikely on paper but works remarkably well in execution.

Release Date & Total Episodes

The drama premiered on December 12, 2025, on iQIYI. It ran for 29 episodes and concluded on December 22, 2025 — a fast but packed run. The complete series is now available for streaming.

Airing Schedule & Drama Format

iQIYI VIP subscribers received a significant head start: the first six episodes dropped on premiere day. After that, the platform released two episodes daily until the finale. The rapid release model suited the drama’s momentum-driven storytelling — it practically demands to be binged.

Speed and Love Chinese Drama Plot Summary

Full Story Without Spoilers

Jiang Mu and Jin Chao (later known as Jin Zhao) grew up as part of the same blended family until age nine, when their parents’ divorce split their world in two. Jiang Mu stayed in China with her mother — sheltered, academic, quietly hopeful. Jin Chao moved to Thailand with her father, where survival replaced stability and the streets replaced school.

Ten years pass. Letters go unanswered. Then Jiang Mu discovers something that changes everything: Jin Chao wasn’t her biological family at all. Her father had adopted him. With nothing legally tying her to him anymore, most people would move on. Jiang Mu books a flight to Thailand.

What she finds there is not the boy she remembers. Jin Zhao is harder now — a mechanic by day, an illegal street racer and underground fighter by night. He doesn’t want to be found. He especially doesn’t want to feel anything for the girl who showed up uninvited into the life he built from rubble. The problem is that she absolutely refuses to leave, and slowly, inevitably, everything he built to keep her out starts to crack.

Main Conflict & Romance Timeline

The central conflict works on two levels simultaneously. On the surface, it’s about whether Jin Zhao’s dangerous lifestyle can be walked back before something irreversible happens. Underneath that, it’s about whether two people shaped by the same fracture — a family that broke them apart — can actually find their way back to each other without destroying what they have left.

Think of it like this: imagine finding an old friend from childhood who you’ve been writing to for years. They never wrote back — not because they forgot you, but because they decided you’d be better off without whatever their life had become. That particular kind of silence, and what it does to both people, is what Speed and Love is really about.

Love Triangle / Key Relationships

The romance does not unfold in a straight line. Lin Sui — a professional racing driver played by Mike Angelo — introduces a third dynamic that complicates Jiang Mu’s world without ever becoming a full villain. He starts as a rival to Jin Zhao and becomes something more nuanced: a man who genuinely cares for Jiang Mu in his own way, which makes the emotional stakes more layered than a standard love triangle usually delivers.

The relationship between Jin Zhao and his father Jin Qiang adds another dimension of weight. The older man’s failings, his drinking, his guilt — all of it feeds into who Jin Zhao became and what makes him so difficult to reach.

Speed and Love Cast & Characters

Main Leads

Esther Yu (Yu Shuxin) plays Jiang Mu — nicknamed Mumu. She’s the emotional anchor of the entire drama. Jiang Mu is warm, stubborn, quietly brave, and deeply loyal in a way that never tips into naive. Esther Yu, previously known for her roles in Hidden Love and You Are My Glory, brings a softer but more emotionally complex performance here. Multiple viewers noted that this role pushed her further than anything she’d done before, and the care she puts into every scene shows.

He Yu plays Jin Chao / Jin Zhao. This is a star-making performance. He Yu plays a man defined by damage and distance, and the slow erosion of his walls across 29 episodes is genuinely compelling to watch. Fans who weren’t familiar with him before Speed and Love have been searching his entire filmography since. The character demands emotional range across very different registers — brooding, tender, explosive, quietly devastated — and He Yu handles all of them.

Supporting Cast

• Mike Angelo as Lin Sui — professional racer, rival-turned-complicated-friend; his character adds texture without becoming a caricature
• Fei Qiming as a supporting figure in Jin Zhao’s racing world
• Sun Meilin as Zhao Meijuan — Jin Zhao’s stepmother; her arc is more emotionally significant than it first appears
• Li Ao as part of the supporting ensemble
• Guan Zijing and Yvonne in secondary roles that round out Jiang Mu’s world in Thailand

Character Relationship Chart

Character	Actor	Role	Key Dynamic
Jiang Mu (Mumu)	Esther Yu	Female Lead	Pursues Jin Zhao across countries; refuses to give up
Jin Chao / Jin Zhao	He Yu	Male Lead	Hardened by survival; resists connection to protect her
Lin Sui	Mike Angelo	Second Male Lead	Rival racer; genuinely fond of Jiang Mu
Jin Qiang	—	Jin Zhao’s foster father	Flawed, guilty, central to backstory
Zhao Meijuan	Sun Meilin	Stepmother	More important than she appears
Nana	—	Jiang Mu’s friend in Thailand	Connects her to Lin Sui’s world

Episode Guide & Recap

Episode List With Release Dates

Speed and Love aired daily from December 12 to December 22, 2025. Episodes 1–6 released together on premiere day for iQIYI VIP subscribers, followed by two episodes per day through the conclusion. The finale, episodes 28 and 29, dropped on December 22.

Episodes 1–5 Quick Recap

Jiang Mu arrives in Thailand after piecing together Jin Zhao’s location through her father’s contacts. The reunion is immediately tense — Jin Zhao is not the warm boy she carries in her memory, and he makes it clear she shouldn’t be there. She ignores this completely. She enrolls in a local language school using Nana’s family connections as cover, finds a reason to stay near his auto shop, and begins the slow work of inserting herself back into his life. Episode 4 delivers the first real moment of unguarded warmth from Jin Zhao — brief, almost accidental, but enough to hook viewers completely. By Episode 5, the pull between them is undeniable and they both know it.

Mid-Drama Turning Point

The mid-series shift hits hard. Jin Zhao’s illegal racing and fighting catches up with him in the worst way possible. A serious accident leaves him with the possibility of a permanent disability. Rather than letting Jiang Mu stay and watch him deteriorate, Jin Zhao does what broken people often do — he pushes her away completely, using every defense he has left. He ends the relationship before it officially begins. He tells himself it’s to protect her. Viewers spent approximately five episodes furious at him for this, which is a sign the writing is working exactly as intended.

The six-year separation that follows — Jiang Mu in Canada with her ill mother, continuing her astronomy studies; Jin Zhao in silence, rebuilding himself without her — is where the drama shifts from sweet to genuinely heartbreaking.

Final Episode Summary

The reunion in Nanjing lands with the emotional weight the whole series builds toward. Jin Zhao has recovered. He has a legitimate place in the racing world now. Jiang Mu returns, and the love story that spent 27 episodes accumulating arrives at its conclusion: a simple, un-theatrical airport proposal that viewers found far more affecting than any elaborate romantic gesture would have been. The final sequences bring the blended family together for Chinese New Year — including a reconciliation between Jin Zhao and Jiang Mu’s mother that carries genuine emotional resonance. The ending closes cleanly, warmly, and completely.

Speed and Love Ending Explained

Happy or Sad Ending?

Happy ending, confirmed. Speed and Love ends with the couple together — married, with both of their family relationships healed in ways that felt earned rather than rushed.

What Happened to the Main Couple

After the six-year separation, Jiang Mu returned to China and eventually made her way to Nanjing, where Jin Zhao had rebuilt his life and his racing career through legitimate means. Jiang Mu, true to her character, had made sure he recovered fully and returned to driving — she was never going to let the story end any other way.

The proposal was quiet and direct, at an airport, which fit both characters perfectly. No balloons. No audience. Just two people who had been on parallel tracks for their entire lives, finally on the same one.

Jiang Mu’s mother, who had resented Jin Zhao for years as a projection of her bitterness toward her ex-husband, delivered one of the drama’s most emotionally complex moments in the final episodes — giving him the black scarf she had knitted for him eighteen years ago and never delivered. The gesture is small and enormous at the same time.

Open Ending or Season 2 Possibility

The ending is fully closed. There are no dangling threads, no unresolved conflicts left as bait for a second season. As of writing, no Season 2 has been announced by iQIYI or the production team, and the story doesn’t require one. This is a complete narrative.

Where to Watch Speed and Love Chinese Drama

Official Streaming Platforms

Speed and Love is available on two primary international platforms: iQIYI and Rakuten Viki. iQIYI is the original broadcast network and offers the full series to VIP subscribers globally via iQ.com and the iQIYI app (available on iOS, Android, smart TV, and web browser). Viki carries the full series and is often the preferred choice for international viewers due to its user experience and subtitle community.

English Subtitles Availability

Full English subtitles are confirmed on both iQIYI International and Rakuten Viki. Viki’s first episode is accessible free without a subscription, making it a zero-commitment entry point. iQIYI requires VIP membership for full access. Both platforms provide good quality subtitles, with Viki’s community translation often noted as more nuanced for emotionally charged dialogue.

Urdu / Hindi Dubbed Availability

As of the time of writing, no officially licensed Urdu or Hindi dubbed version of Speed and Love has been confirmed. Unofficial fan-dubbed versions may circulate on YouTube or Dailymotion, but for the highest-quality viewing experience with accurate translation, the English-subtitled versions on iQIYI and Viki are strongly recommended.

Speed and Love Drama Review & Ratings

Story & Character Development

The first two-thirds of Speed and Love are as good as modern Chinese action romance gets. The Thailand setting brings a visual freshness that immediately separates this from the usual C-drama cityscape. The neon-lit night scenes have a stylized quality that reviewers consistently describe as cinematic — more film than television. The action sequences, both the boxing and the racing, are technically accurate and genuinely exciting, not polished-to-irrelevance the way many dramas handle physical conflict.

The final third, as several long-form reviews note, shifts into more conventional territory — the separation arc introduces the kind of noble idiocy (refusing to let someone help you for their own good) that divides C-drama audiences. Some viewers found it frustrating. Others found it the most emotionally realistic part of the entire story. The honest answer is that both responses are fair, and the drama earns the criticism and the praise in roughly equal measure.

Romance Chemistry Analysis

The chemistry between Esther Yu and He Yu is the defining quality of Speed and Love, and it’s essentially impossible to overstate. Whether they’re in a garage, a race circuit, or standing quietly on a rooftop in Bangkok, the tension between them is constant and electric without ever feeling manufactured. The progression from childhood affection to complicated adult feeling is handled with care — you understand exactly how they arrived at every emotional point, which makes each scene land harder.

Viewers who describe their dynamic use words like “addictive,” “undeniable,” and “once in a lifetime chemistry.” Several noted they kept watching edits of the drama between episodes just to manage the waiting. That’s the specific kind of hold a drama has when the leads are genuinely extraordinary together.

MyDramaList Rating

Speed and Love holds an 8.5 out of 10 on MyDramaList, scored by over 14,000 users, placing it in the top 600 dramas on the platform across all time and all countries. For a drama that premiered in December 2025, that is an exceptional position to hold this early.

IMDB Score

IMDB currently rates Speed and Love at 8.0 out of 10, with consistent praise in user reviews for He Yu’s performance, the cinematography, the action sequences, and the central romance. Critical notes tend to focus on the separation arc in the final episodes.

OST & Soundtrack List

Opening Theme

The opening theme sets the emotional register for everything that follows — equal parts restless and tender, which maps perfectly onto the two leads’ dynamic. It has the kind of melody that comes back to you at random intervals days after watching.

Ending Song

The ending theme shifts in emotional weight as the series progresses, landing hardest in the separation arc episodes where it closes out scenes of deliberately chosen silence. It has been widely praised as one of the more memorable C-drama OST tracks of the 2025 drama season.

Most Popular Romantic OST Moments

One standout scene that multiple reviewers single out: Jiang Mu singing “The Moon Represents My Heart” — a Chinese classic — to Jin Zhao in a moment of vulnerability. The scene uses the song’s weight of cultural memory in a way that feels completely natural and deeply affecting. It’s the kind of sequence that stops you mid-watch and makes you pause before continuing. The OST across all 29 episodes was consistently praised for being purposefully composed rather than generic background fill, with each track chosen to amplify a specific emotional moment rather than simply accompany it.

Best Romantic & Emotional Scenes

Top Fan-Favorite Moments

These are the scenes viewers keep returning to in edit compilations and discussion threads:

The airport pickup in Episode 1, where Jin Zhao collects Jiang Mu and she clings to his familiar scent on the motorcycle — the whole drama in one image. The garage scenes where neither of them says what they mean. The birthday midnight scene where Jiang Mu appears at his autoshop at midnight, just to be there. The swimming pool dream sequence. And the final airport proposal — which works precisely because it doesn’t try to be more than what it is.

Most Viral Social Media Clips

The intimate tension scenes between the two leads generated consistent engagement on social platforms throughout the drama’s run. The racing and boxing sequences, particularly a backward-across-the-finish-line moment in the racing arc, circulated widely in the first week of broadcast. He Yu’s transformation scenes — contrasting the elegant boy in early flashbacks with the hardened man in Thailand — became a recurring feature in fan edit compilations that kept the drama trending well after its finale.

Romance Timeline Breakdown

This is the arc that most reviews skip over without mapping properly. Tracking it is worth the effort, because the drama’s emotional payoff is directly tied to how carefully the relationship is structured across all 29 episodes.

First meeting (age 9): Two children in the same household, beginning a sibling bond that will define both of their lives without either of them knowing it yet.

Separation (divorce, age 9): The divergence point. Two parallel tracks, as the title states. Jiang Mu writes letters. Jin Chao doesn’t answer. Life goes in opposite directions.

The secret (age 19): Jiang Mu discovers Jin Chao’s adoption and flies to Thailand alone. The reunion is tense, charged, and immediately destabilizing for both of them.

Thailand arc (Episodes 1–20): From reluctant coexistence to genuine closeness. The feelings become undeniable before either of them addresses them out loud. Jin Zhao’s dangerous lifestyle escalates. Jiang Mu refuses to leave. Every moment of warmth is followed by a moment of self-protection.

The accident and separation (Episodes 21–24): Jin Zhao’s injury. His decision to push her away as an act of love. The six-year gap. Jiang Mu in Canada. No contact. Two parallel tracks again, but this time chosen.

Reunion in Nanjing (Episodes 25–29): The return. Recovery — physical and emotional. The quiet proposal. The family reconciliation. The two tracks finally merging into one.

Every stage of this arc is mapped carefully, which is why the finale lands with the weight it does. The drama earns its ending.

Dramas Like Speed and Love

If Speed and Love has you looking for what to watch next, these are the closest matches across different angle:

For the same bad-boy-meets-good-girl energy with exceptional chemistry, Hidden Love (also starring Esther Yu) is essential. You Are My Glory delivers similar slow-burn sweetness. For action-forward romance with genuine stakes, Go Ahead covers the adopted family dynamic from a different angle with equally strong emotional payoff.

For the Thailand/international setting and edgier romantic tension, I Will Miss You and Love in the Air (Thai drama) scratch similar notes. For fans of He Yu specifically, his earlier work is worth exploring now that he has a wider international audience.

Behind the Scenes & Filming Locations

Shooting Locations

Speed and Love filmed across multiple real locations chosen to reflect the dramatic contrast between the leads’ two worlds:

In Thailand (primarily Bangkok and surrounding areas), the production captured the street racing circuits, underground fight venues, Jin Zhao’s auto shop, and the neon-lit night scenes that give the drama’s first half its distinctive visual character. Bangkok’s 24-hour energy — its markets, its rooftops, its late-night corners — becomes a character in its own right.

In China, scenes depicting Jiang Mu’s academic and family life were filmed in Nanjing and Hainan. The Nanjing sequences in the final episodes carry a different visual tone — cleaner, more domestic, which mirrors where both characters have arrived by that point in the story.

Fun Facts From Production

Principal photography began on November 22, 2024, and wrapped on April 2, 2025 — a shooting period of approximately four months across two countries. The technical accuracy in the racing sequences was specifically noted in early reviews: the production team committed to authentic race mechanics rather than stylized approximations, which pays off in the tension those scenes generate. He Yu’s physical transformation for the role — the fighting training and the changed physical presence required for Jin Zhao — drew significant attention in pre-release coverage and during the drama’s run.
