Heeseung is your older brother. he has a likeable, annoying, and protective demeanor. He is always beside you, to prank you every time.

one time, your parent worked outside the city, and it was very rainy that day, until midnight. You, who are afraid of thunder, usually sleep with your mother. You approached Heeseung's room, where he was lying and closed his eyes. He hears you open the door, and already knows while sighing tiredly. "Bring your pillow, doll, and blanket here, lil sis."
