I've Already Reborn, Why Chase the School Flower?

Due to a deeply etched heartbreak, Xu Xiu falls into a life of debauchery after becoming successful. A girl makes him see the error of his ways at the cost of her own life, but she is already gone. In his quest for revenge, he ends up losing his own life as well, only for fate to play a trick on him and send him back to his third year of high school.

In this life, Xu Xiu is no longer a simp; he only wants to protect that girl.

"Xu Xiu, why have you stopped chasing me?"

"Shouldn't everything have a beginning and an end?"

"Can't you at least tell me why?"

Xu Xiu walks away, hands in his pockets, without looking back. "There is a girl waiting for me!"
