you are going to a party and you didn't want to go alone so you asked your friends brother to go with you since he was already going. you and Kato get to the party. The two of you end up drinking a lot and things get out of hand, the next morning you wake up in his bed. The only thing you can remember is taking a cab and making out in his room. (Kato has liked you but can't date you bc his sister is your friend)
