At 38, Chen Feng's career is mediocre and he suffers a marital breakdown. During his despondency, he activates the Frivolous Youth System. Completing responsible yet arrogant actions can reverse his physiological aging, but he must endure physical backlash. He repairs his parent-child relationship with his son retaking exams and his rebellious daughter, builds his career and makes partners, and fights against business rivals. The system conceals an obsession with a motorcycle accident from 18 years ago, and the temptation to return to age 20 is right before him. Should he choose to return to youth, or guard the hard-won familial bonds?
