Xiao Bo is a courier who rides a beautifully restored classic motorcycle, delivering packages while scrimping to fund his nephew’s ear implant surgery. He crosses paths with Ye Jin, a driven CEO who has fallen out of love after her fiancé’s betrayal and, as a result, has developed an odd aversion to the color yellow—an affectation tied to a scene she witnessed on a yellow notepad. Her mood and moodswing set the tone for a company-wide purge of yellow items, which stirs up tension and drama in the office.
When Ye Jin contemplates expanding her family through in vitro fertilization and a surrogate, she entrusts her assistant, Jenny, to quietly locate a suitable sperm donor. Jenny arranges a ruse—a fake job interview where several hopeful candidates think they’re vying for a personal assistant position. Among the pool of applicants, Xiao Bo’s interest is piqued not just by money, but by the chance to work with a person he senses is both formidable and fragile.
A dangerous twist enters when a former Ye Jin employee, furious over a dismissal for falsifying information, tries to stab her; Xiao Bo intervenes, saving her, and this act kindles a fragile, dawning connection between them. Ye Jin decides to interview Xiao Bo for the assistant post, and she is won over by his grit, even as his disorganization and chronic lateness threaten the arrangement. Yet a shared moment happens when a traffic jam forces a delay: Xiao Bo’s friend brings his motorcycle to shuttle them to a crucial meeting with a big client who adores classic bikes. Ye Jin, impressed by his ability to improvise and ride, agrees to partner with him, seeing in him a partner she hadn’t expected.
Later, Ye Jin’s father, a man battling Alzheimer’s disease, is found at a care center and wrangles Ye Jin’s mood as she confronts the neglect she’s shown him. Xiao Bo challenges Ye Jin on how she treats her father, and she feels a sting of guilt; he resigns in a flare of anger after she pushes him away, and she contemplates a harsh penalty for breaking the sperm-donation arrangement. Yet the conversation lingers, as Xiao Bo reveals why he’s so determined to earn money: to help his nephew. The two share wine and sleep beside one another, a quiet moment that signals a turning point in their relationship.
The couple heads to Paris for the IVF process, while Ye Jin’s friend notes that both of them share a deep, unspoken love. Ye Jin remains determined to carry a child on her own, even as Xiao Bo’s influence remains strong in her thoughts. The IVF procedure is ultimately successful, and Xiao Bo, watching Ye Jin interact with children at a party hosted by his friend Sophie and her husband, finds himself drawn more deeply into her world.
Xiao Bo’s nephew’s ear surgery goes smoothly, but his mind won’t drift far from Ye Jin and the unborn child. He composes a storybook about their love and ships it to France, where Ye Jin has stayed through the pregnancy—unaware that she has suffered a miscarriage and slipped into a deep depression. When the package arrives, it deepens her pain and she vanishes from her home, leaving Sophie and her husband worried.
Xiao Bo arrives at the same house and discovers Ye Jin’s heartbreak and isolation. In a tense moment, Sophie’s husband finds Ye Jin near a cliff, and Xiao Bo pleas with her, sharing a parable of a fallen soldier who dies skydiving with his older brother, offering that if she wants to die, he will die with her. The two embrace, and Xiao Bo’s parachute opens as they soar into the French sky, landing on a cathedral’s steps and sharing a kiss that marks a hopeful turning point. The epilogue closes on a warm note: Xiao Bo and Ye Jin are shown with two babies, hinting at a future filled with resilience, family, and renewed love.
