A Prized Uniform and the Four Gold Stars
Jiang Mu starts off the morning looking for every possible excuse to stay in Jin Zhao's space, claiming her room cooling setup died completely. Even when he offers to fix the unit, she insists the rest of the appliances will give out next. Jin Zhao gives her a ride on his bike to cram school, where she casually mentions that open house day requires a guardian to show up.

Back at the garage, Jin Zhao pulls out a crisp, carefully preserved school shirt that the crew has not been allowed to touch. Over lunch, he tosses it right to Jiang Mu to try on.

Later at band practice, Nana spots the collar details right away.

Nana explains that the four gold stars pinned to the crest belong exclusively to regional competition winners handpicked by the head teacher. The revelation hits Jiang Mu hard. She always knew him as a grease-stained mechanic, not a prodigy who skipped college entrance exams.

When she brings her math homework to the shop so he can write out step-by-step annotations, she quietly asks why he dropped out. Jin Zhao tightens up instantly, dodging the question with total silence.

A Stray Pup in a Cage and Childhood Scars
In the garage courtyard, Sanlai introduces Jiang Mu to a tiny pup rescued after being abandoned by its mother.

The little dog stirs up painful childhood memories for Jiang Mu, who once hid a stray puppy named Lightning inside a cardboard box before her mother forced her to give it up. Watching the shivering pup, she decides on the spot that she wants to raise it.
Jin Zhao shuts her down immediately. As they walk through the alleyways, he argues that caring for a pet out of sudden pity is irresponsible when their living situation is temporary.

The argument quickly turns personal. Jin Zhao tries drawing a hard boundary by treating her like a temporary guest, which pushes Jiang Mu past her breaking point.

She calls out his emotional walls, reminding him that just because their blended family split up and they share no blood ties does not mean he gets to wipe away their bond whenever things get uncomfortable.
Naming Lightning and Facing Garage Jealousy
Sanlai calls Jin Zhao out for acting dense, asking how he plans to handle things if Jiang Mu sees him as something far more than just an older brother. Jin Zhao refuses to answer, but his actions speak louder. He quietly arranges to adopt the puppy and brings it back to the repair lot.

Cradling the puppy in her arms, Jiang Mu names him Lightning after her childhood pet. The tough guy facade slips away as Jin Zhao looks down with a quiet, suppressed grin while she teases him about taking their new pet out for a walk.

The soft moment gets interrupted when Wan Qing shows up at the shop lot. Using her father's racing standing as an icebreaker, she offers Jin Zhao a polished red apple to get on his good side. Jin Zhao rejects the gesture flatly, stepping back without hesitation.

Once Wan Qing leaves, Jiang Mu picks up the apple and takes a bite right in front of him. When Jin Zhao snaps that he does not take handouts from strangers, Jiang Mu smirks right back, telling him that one day a girl will show up who can actually keep him in line.
Math Homework, Grudge Matches, and Circuit Shadows
Back inside the shop, young Xinxin comes home dragging her feet over a poor test score. The older mechanics struggle to read the paper, so Jin Zhao pulls up a chair and goes over every mistake with her. He quickly notices that Xinxin threw simple questions on purpose.
Xinxin confesses that scoring first place would force her to deliver a speech in front of the entire student body, which terrified her. Instead of scolding her, Jin Zhao signs the paper and gently advises her to be honest with her teacher rather than fudging her test scores.
That evening, Jin Zhao drives Xinxin home and ends up stopping by the circuit area where racers gather for late-night tuning. The venue is packed with modified sports cars, and Jiang Mu runs into Ling Sui, who offers her a drink amid the roar of engines.
The electric mood shifts when a bruised driver pulls Jin Zhao aside in the shadows, begging him to race as a ghost substitute. Jin Zhao turns him down flat, but rival racer Pan Kai tracks him down right after to demand his contact details. Gripping the wheel, Jin Zhao stares out into the neon glare as his past life threatens to pull him back into the circuit fray.
