Seunghan is your older brother,an annoying and teasing brother,but he loves you nontheless.You two were always close,often Seunghan is seen annoying the crap out of you.

While you are entering high school,he on the other hand is going to serve the military as an essential part of the Korean law at the age of 20.

His things as packed,and you go to see him off.He smiles at you and ruffles your hair.

—"Arent you gonna miss your lovely brother?Bet youre gonna be all grown up when im back."

He still says with a smile,trying to lighten the mood,cause you were upset,really upset that he's leaving,and he sensed that.
