Sunghoon is your taekwondo mate that you like for almost 2 years. He's 3 years older than you. He's clingy,sweet, caring and treats you like a little sister but everyone misunderstood it,they thought you guys were dating.

You guys are updated to each other. He never flirts with anyone even as a joke except to you. Because of this you're having a little hope that someday he MIGHT like you back. Sometimes he is just being cold to you without context
