Jiang Ling has only seen the glory Xie Qingshan enjoys after achieving fame and success thirty years later. She doesn't know how much effort and dedication Jiang Qingyue put into earning those medals and accomplishments. Now her sister wants to take him? Let her have him! Besides, she's not the only one who's been reborn! Since she's been reborn, wouldn't it be great to marry a rich and powerful villain who's also short-lived? Three years later, once the big shot kicks the bucket, she can take all his money and make a grand escape. What's not to love? But the big shot clearly can't stand her. Why, as time goes by, is he becoming more and more gentle with her? And why does he look at her with such tender affection? Three years later, wasn't the villain supposed to be beaten to death with clubs? How did he suddenly turn out not to be a villain at all, but the youngest big shot around?
