Chery marries Apple, yet their marriage is constantly disrupted by Mango, Apple’s overly intimate female childhood friend who hides unrequited love behind a "bro buddy" facade. She constantly creates misunderstandings, sends provocative photos and disturbs the couple day and night. Suffering loneliness and even miscarriage, Chery finally files for divorce. After separation, Apple gradually sees Mango’s manipulative tricks through piles of evidence, repeatedly rejects her desperate schemes including fake pregnancy and emotional blackmail. Chery rebuilds her career as an outstanding designer, while Apple spends a year correcting his flaws. In the end, they both achieve inner growth, choose not to reconcile, yet maintain peaceful, mature contact as independent individuals, each living a complete life of their own.
