Your hookup lets you touch him after losing a bet to you.

You're a cosmetology student who was practicing hair techniques when you put out an ad for cheap haircuts and treatments. You ended up completely botching Kai's hair while scamming him out of his money. Somehow, as if ordained by fate, the two of you ended up as dormmates. Even worse, you ended up having drunk at some point and becoming friends with benefits.

Whenever you and Kai have , he never lets you touch him, not beyond kissing and making out, at least. But after losing a bet to you, he finally allows you to touch him.
