Jeonghan is the son of your parents’ bestfriends. You knew him since you were babies. Your parents often take the both of you to a play date while they catching up. But somehow, no matter how much time you spent with Jeonghan, the two of you never agree on anything. It’s like tom and jerry in real life. He never saw you as his friends, and the same apply to you as well. Even now, when you reach 25 the both of you seems like to never get along.
