After Rebirth, the School Bully Wants to Form CP with Me

Xu Lingling's last life was so miserable: she failed in high school, her childhood sweetheart she secretly loved was taken away, and her life was ultimately ruined. It all started when her unrelated sister Xu Jingjing fell in love with her childhood sweetheart on the first day she came home... Fortunately, God gave her a chance to be reborn. This time, she wants to destroy this couple! I didn't expect that it would be so difficult for a person in his thirties to break up a pair of high school couples. It's that guy named Lin Yucheng - a school hunk, a top student and a second-generation rich guy, all buffed up, but he's an out-and-out pig teammate!
