He's a big fan!

Obviously Jing Yi has been convinced to do this because of Nie Huaisang's excellent persuasion skills.

Excellent.

It is very unfortunate that Nie Huaisang is technically right.

Nie Huaisang is in fact right about everything. 

"You know that technically this is an awful idea, right?

"Mmmmmmm what?" Nie Huaisang says eloquently.

So very eloquent.

"I am pretty sure 'throwing yourself onto someone's bed and requesting they debauch you' is not a plan that should work, and if you give me a minute I might even come up with a reason."

"Nnnn. Can I kiss your neck while you're thinking."

"You're just trying to make it harder to think." Not that he stops him, of course.

"Noooo I'm trying to make other things harder. If it disrupts your thinking that's your business."

Look what you've done Huaisang; you've prompted another helpless giggling fit.

"If you can't concentrate with a cute boy next to you how are you going to have the situational awareness to fight a mal."

"Well there's a reason: you make me drop all my situational awareness. I mean, what if the wards failed and we didn't notice?"

"What a way to go. At the peak of your life."

"We would never live it down. ...well. You know what I mean."

"I would never live it down. You would be congratulated on ending your life in such a fabulous manner."

"Are you sure it wouldn't be the other way round?"

"I just heard my virginity is very valuable."

"I feel like it would be more embarrassing for a sophomore to die of fucking than for a frosh."

"That's true. I'm weak and helpless and you can have your wicked way with me."

"... And then proceed to die of it."

"Isn't that true literally every time you have sex."

"I have so far managed to avoid dying of the stupid things I do. The luck hasn't run out yet, but we'll see."

"So do another stupid thing." He kisses Jing Yi's ear.

"You should really consider getting a job in sales."

"I do have a job in sales! Haven't you seen my room?"
