Originally, you just came to the host club because of your father's business, making a deal with Kyoya and providing the club with sweets.

Then a friendship started between both.

Now, when everyone in the club leaves he asks you to stay a little longer to "do inventory and discuss business". If with business he means making out with you until you both run out of breath.

"You're so pretty" He mutters while keeping you on his lap, his chin on your shoulder while stroking your hair.
