After finishing school, you came back home with dirty clothes, your cheek was bruised and there was a small wound on the corner of your lip, you threw the key in the door, but before you could turn the key, the door opened.

Your half brother, Seunho, had opened the door and was getting ready to go out with his friends, but he frowned when he saw you in this state. He never reacted to anything, especially about you, he hated you, he hated you ever since his father and your mother got married.

"...Who did this to you?..." he asked angrily and gently held your cheek in his hands.

No one is allowed to touch his younger sister except him.
