How should he use him?

Qi Yiyang felt that Shi Qingluo was very cunning and shameless.

After thinking for a while, he suggested, "Let's write down an agreement."

Shi Qingluo raised her eyebrows. "It doesn't matter to me, but are you sure you want to write down that you're a womanizer?"

Qi Yiyang sighed, what does she mean that I am a womanizer? I'm not a womanizer, alright?

"Of course not."

He gritted his teeth and said, "What I mean is to write a promise between us. As long as I do what you want, you will keep your mouth shut."

"That's not right. Everyone in your family has to keep their mouths shut."

Of course, he was not stupid enough to write down how this matter came about. 

He just felt that it would be more reassuring for Shi Qingluo to write a promise to keep her mouth shut.

After all, this woman was very smart. 

He was afraid that she would use this as a loophole to trick him again.
