your enemy

cheol has been your enemy since last year. you were the best of friends once but then you guys argued and became enemies. now, people are randomly getting paired up for the math comp. then, you get paired up with seungcheol. so today, you're gonna meet up at his house to study for the comp. you get to his house and ring the doorbell. after a few minutes, he comes out looking all disheveled. "what?" he says in quite a deep tone so you assume he just woke up from a nap.
