The first time they meet, she bumps into him. The second time they meet, she agrees to a marriage contract in exchange for his help in her bid for revenge. But… he becomes addicted to loving her.

During his first attempt, he flies a helicopter domineeringly; in his second attempt, he arrogantly removes all his love rivals; in his third attempt, he tries to tie her down using a cute child. Youxuan replies with a plain resounding ‘no’ all three times.

In the end, Shan Hanjie takes one look at her, grits his teeth, and plops onto the ground. “Babe, you dropped your prince charming, please bring him home!”

Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout.
