Fall in Love at First Kiss

Jiang Zhishu rides his bike when Yuan Xiangqin trips on the stairs and grabs his tie, nearly sending both of them into a comic catastrophe. Their lips meet in a charged, accidental kiss that marks their very first contact. The moment hints at a complicated dynamic between a genius and a determined newcomer.

Xiangqin encounters Zhishu again when he speaks at a school assembly about his project in Boston. The crowd learns he is extraordinarily smart, allegedly with a 200 IQ in the A class. The meeting plants the seed of mutual fascination despite their initial wariness.

Two years pass and Xiangqin obsesses over Zhishu through social media, following every update about his rise from F class to A class. When he is seen walking toward the A building and hundreds of fans chase after him, she sees a chance to confess as the A-class gate closes. She gives herself a hard ultimatum to reveal her feelings before it's too late.

During a planned fire drill that shuts down technology, Xiangqin finally reaches the A gate and confesses to Zhishu. He coldly rejects her in front of the watching students, leaving her humiliated. The moment hardens the social divide between them and reshapes their relationship.

All A-class students capture Xiangqin's confession on video, and the principal scolds her for wasting Zhishu's time. The school community mocks her embarrassment, increasing the stigma around her attempts. The incident plants a resolve in Xiangqin to prove herself against the odds.

Xiangqin's house collapses due to poor construction, thrusting her into the spotlight once more. She taunts Zhishu, claiming an F-grade student can crack the top 100 on a mock exam, and he reluctantly agrees to the challenge. This bet becomes the catalyst for a deeper connection between them.

Xiangqin moves into her father's friend's house, unaware it is where Zhishu already resides. Over time, Zhishu's mother intervenes, encouraging their interactions and helping them grow closer. Their relationship moves beyond rivalry as they navigate school and home life.

To spare Xiangqin from further embarrassment, Zhishu agrees to tutor her for the mock exam after his mother helps broker the deal. Through late-night study sessions, Xiangqin climbs to 100th place while Zhishu remains at 1st. The tutoring deepens their rapport even as their rivalry remains.

At an athletics carnival, Xiangqin is publicly exposed as Zhishu's resident and the embarrassing video is streamed, escalating the tension between them. They quarrel in front of everyone, and Zhishu abruptly kisses Xiangqin before storming off. The moment adds romantic tension to their fraught relationship.

Two years later, Xiangqin supports Zhishu at his mother's request but he distances himself as he pursues his veterinary and business ambitions. He marries a business partner to merge their enterprises in a bid to save his father’s company, prioritizing duty over romance. Xiangqin watches from the sidelines, feeling dismissed.

Zhishu's father and mother voice disagreement with his decision to marry for business, urging him to follow his heart. The family conflict underscores the struggle between personal happiness and family obligation. Xiangqin remains on the fringes as the power dynamics shift.

Another year passes and Xiangqin checks Zhishu's social media, arriving at a school hall post that seems directed only at her. She enters the hall and finds Zhishu alone, and learns that only selected people can see his messages. He unexpectedly proposes to Xiangqin, and she accepts.

A flashback reveals Zhishu tutoring Xiangqin and discovering the love letter she wrote. The scene confirms that Zhishu has always been in love with Xiangqin, even as they grew apart. The hidden history merges with the present as their feelings are finally acknowledged.

The story closes with a brief post-credits image of Xiangqin and Zhishu’s wedding, sealing their long journey from rivals to partners. Their union reflects the transformation of their relationship from infatuation to lasting love.
