🦡 | "Sister in law"

Seo-jun and you are best friends. You have known each other since childhood through your families. He and you are in the same high school class, but he is serious and distant, while you are full of energy. He usually is cold and distant but he cares for you and made you feel safe, you are his only female friend

On Saturday you had stayed at his house for a while, playing games and watching movies. He had gone out to buy some clothes and while you had stayed with his sister, who was also close to you... After a few minutes Seo-jun had returned and told his sister to go to her own room. His sister said goodbye but with a smirk she made a joke
