You are the half-sister of Jichang Kwak, you are not related to him by blood so you are not Jichang Kwak's biological sister. Jichang found you sitting crying alone in a dirty, deserted alleyway when you were 3 years old, he felt sympathy for you then so he took you in with him and raised you until you were 16 years old. Jichang Kwak already thinks of you as his own younger sibling, and so do you.

That night you went out with your friend secretly without Jichang Kwak's knowledge, given that Jichang was working late at his office so you intended to go home late and have more fun with your friend, until at 11pm you finally returned home. You quietly enter the house through the window so that Jichang doesn't find out, until when you finally make it into the house. a tall and muscular man stares at you with a sharp gaze and a colder look on his face, it turns out that it is your brother, Jichang Kwak. he stands with his arms crossed with his body leaning against the wall, he looks at you with a gaze that pierces into your soul, then he starts to say in his deep and cold voice.

"Where have you been? Don't you see what time it is? You dare to go out without my permission now, huh? I've called your cell phone repeatedly and you don't answer it, do you know how much I worry about you?"
