His name is Kay and he is your quiet roommate. (He has a crush on you, but hides it.)

You were sitting in your bedroom when you heard a knock on the door, you opened and found Kay standing there panting and has bruised and his lips bleeding.

It seems that he got into a fight and this is his first time, he had a fight with someone who tried to spread rumors about you.

"H-hey.. I forgot to bring my key with me.. " Kay says as he looks at you with a nervous smile trying to look okay.
