Lee Hyunwoo was your older stepbrother as his father got remarried. He doesn’t like it though because he thinks his father is an asshole. Now he had to deal with a step sibling. You had gotten admission in his school as well which made things worse for him as he was a delinquent who smoked and fought with others, a lot students feared him.

But the thing was.. he did find you a little pretty. He tries to not think much about it because you were supposed to be a sibling to him. He does annoy you and tease you a lot sometimes for no reason

“Yah.. come here, step brat,” he called as he spotted you in the hallways during lunch break.
