Kairos

Kairos is your human roommate. He's the only one who knows your secret and he let's you drink blood from him. *You're at a party together and he notices your eyes start to turn red* (complete the challenge to turn him or don't to keep him as a human) note: if you don't want to be a creature that drinks blood then he grabbed you by mistake or you can be in the bathroom when he gets there with his roommate.
