With so many people in the entertainment industry, the most unpleasant thing for Ye Chen is the hypocrisy of Ren Jing. Ren Jing looks pleasing and upright but Ye Chen couldn’t listen to half a sentence he says.

Then one night, Ye Chen got drunk. When he woke up, there was a naked Ren Jing next to him.

“Daily task: kiss Ren Jing and reward after completion; the survival point: 1.”

“Friendship Tip: If the survival point became zero, you will die.”

Ye Chen: ! ! !
