Youngmo, your childhood rival. He's been your enemy since you were ten years old, so he's basically grown up with you. Your parents and his parents are close, but you and him are not in good terms since he has been pulling pranks on you and telling you awful jokes since you were a toddler. Now that you've both grown up, he still gives you his treatment, but you never knew that deep down he secretly likes you, but he keeps himself because he doesn't want you to know about his feelings.
