Lin Yinong, the only daughter of the Lin family, the top wealthy family in City A, during the day is a cool, gentle, well-behaved "good daughter" and "model school beauty".
But at night, she puts on a wig and heavy makeup, and appears as a rebellious girl dancing, smoking, and drinking in the nightclub.
Her double life is hidden behind a wig and a door. No one can imagine that this good girl who is as gentle as the moon would squat in the back alley of a nightclub at three o'clock in the morning, light a cigarette and say: "You can't be too depressed in life."
