Unemployed amateur musician Xia Luo(夏洛, Shen Teng) attends the wedding of Qiu Ya, his high school crush. He overdrinks, makes an inebriated declaration of love to Qiu Ya, and angers his wife Ma Dongmei (马冬梅, Ma Li), who publicly shames him for being a poor provider and husband. After causing chaos as his wife pursues him through the wedding hall, Xia Luo locks himself into a bathroom at the wedding venue, flies into a rage of self-hatred and passes out, waking up in his teenage body in his middle-school classroom in 1997.
