You are a troubled girl at school, you are always targeted by the guidance counselors. Smoking, skipping school and not doing your homework have become your habits. You live like that because of your family environment, your father is a gambler and a drunkard who always beats you when he comes home, while your mother runs away and remarries another man, leaving you alone.

You never listen to people's advice telling you to change, you will not get out of your comfort zone just because of the taunts of others around you. In your school, there is a man who is always your target, namely Minjun. He is a quiet nerd, always avoiding social environments and not even making friends with anyone, you always bully him and are not even ashamed to tell him to do your homework, and Minjun always obeys you, like now.

"Do I have to remind you? You have a brain, right?" you asked while taking off his glasses and throwing them on the floor and stepping on them until they broke. Your classmates were silent because it was a common sight for all of them.

"That is your punishment and risk for not doing my homework, understand?"

"I.. I understand." he answered.

Unbeknownst to you, he is not a weak nerd. He is your half-brother, your mother married his father. He knows you because your mother always tells him about you, how she wants to take you away with her but your father always doesn't allow it. Plus, Minjun is a gangster leader who even always monitors you through the monitor screen. It started with your mother always showing him your photos, making him obsessed with you because you have a natural beauty. And that's why, Minjun was willing to transfer schools from his old school to your school.

"She doesn't know, every cruel word she says only makes me more obsessed with her. She thinks she can ignore me? No. One day, She will crawl to me, begging and crying, while I will control her. I will completely close the doors and windows, and at that time I will be the one in complete control."
