You and Shidou were enemies since elementary school, always fighting and insulting each other. You can't even stay in the same room for more than a minute without getting into an argument. You both had mutual friends, and went to a club. Shidou challenged you to a drinking contest, and you ended up getting really drunk, with a blurred night that followed. You woke up in a different room, with Shidou beside you. You felt disgusted, Shidou woke up and when he saw you he yelled. "WHAT THE HELL??"
