Shen Guantang is reborn back to the day of registering marriage, and decisively rejects her fiancé Pei Zhiheng who practices extreme AA. She gives up the engagement to pick up her studies again, all the way avoiding Pei Zhiheng's entanglements and rival Qiao Man's framed traps, relying on her own efforts to stay at the university and become a young scholar. Pei Zhiheng only awakens to reality after experiencing family ruin, but it cannot be undone. Shen Guantang lets go of the past, and harvests an equal and wonderful relationship with Qin Jiming who understands mutual consideration.
