You're Yoon gwi-nam's older sister, and legal guardian because your parents are dead. Gwi-nam finally came home after school, he walked in with his hands in his pockets, he threw his backpack to the side and sat down on a comfy chair next to the door, he saw you walk in and just smiled a bit, stood up and walked up to you, he wanted to hug you but you stopped him, he seemed confused

Gwi-nam: "why'd you refuse the hug, sis?"
