Classroom Vandalism and the Confrontation on the Track
The relief of finishing monthly exams evaporates the moment students find Lin Zhixia's desk crammed with garbage and stained with red ink. The open malice leaves Lin Zhixia shaken and struggling to understand why anyone would target her so aggressively.

Zhang Yubai refuses to let the incident slide. He steps in with immediate reassurance, promising Lin Zhixia that he will uncover whoever pulled the stunt. Later by the running track, Zhang Yubai corners Kong Geng, calling out his hostility. Kong Geng deflects the accusation with smug defiance, pointing toward a campus security camera to dare Zhang Yubai into throwing a punch that would trigger disciplinary penalties. Zhang Yubai holds his temper, delivering a firm warning instead of taking the bait.

Despite the hostility inside the school walls, Lin Zhixia finds steady backup outside the gate, where classmates roll up on bicycles to escort her safely home.
Confessions in the Office and Hidden Loneliness
Tensions spill beyond the schoolyard when Kong Geng's parents lodge a formal complaint about outside troublemakers threatening their son near the gates. Summoned to the administration office, Lin Zhixia and Zhang Yubai find themselves wrongly blamed for hiring neighborhood toughs.

Before disciplinary sanctions land on innocent shoulders, Sun Fuxuan steps through the office door and confesses that he contacted Brother Li's crew to warn Kong Geng off. The admission stuns the head teacher, who summons Sun Fuxuan's mother, Professor Shen, to the school.
After leaving the office, Sun Fuxuan and Lin Zhixia sit together on the staircase landing. Sun Fuxuan admits that his wealthy, busy household left him isolated for years, leading him to buy fake company from street acquaintances with pocket money. Lin Zhixia shares her own past struggle of doing favors just to fit in, helping both recognize what dependable friendship actually looks like.

Alley Standoff and a Warm Turn Toward Music
Cutting ties with street crews rarely goes smoothly. Brother Li corners Sun Fuxuan in an alleyway, demanding cash or physical violence as the price for walking away.

Just as Brother Li raises a hand, Zhang Yubai and the squad arrive en masse, standing shoulder-to-shoulder in school uniforms to back Sun Fuxuan. Faced with a coordinated group and swift institutional reports, the thugs back off without landing a hit.
The emotional resolution continues at home. After Lin Zhixia reaches out to explain Sun Fuxuan's isolation to Professor Shen, Sun Fuxuan returns to find his mother waiting with a bowl of homemade seafood porridge, quietly repairing their family dynamic.

Back at school, the relief transforms into creative energy. Gathering in the club room to plan for the upcoming campus festival, the students decide to assemble a band, setting a hopeful tone for future milestones explored in the Genius Girlfriend Episode 20 Recap and the Genius Girlfriend Episode 24 Ending Breakdown.
