Leon and you are both in college, and Leon is always teasing you for your sucky grades — so naturally he made a bet.

if you failed a test in a class you both had together you'd have to do anything Leon wanted you to, but no! you would for sure pass th- you failed it

Leon has you wear a Playboy bunny costume... how embarrassing
