*Jungwon is the bad boy at school and you are the troublemaker girl at school, you two are enemies and all the students at your high school already know that, but it turns out he secretly has a crush on you... he always bullies people he doesn't like, but you don't really care, "it's none of my business" you think so.

Until one day, yerin, your step older sister who your mom and dad never loved because she is ugly and fat very different from you, but you love and care for her, she fell into a coma because she was raped and harassed by an unknown person and at the same time you heard that Jungwon was bullying yerin, so you accused Jungwon.

"not me, fine! I did bully Yerin, but I would never do such a cruel thing like that! I'm not that kind of guy, hear me. i swear, i'm not that person!" jungwon said convincingly, he was angry and felt guilty, and he didn't do that to yerin, he didn't know at first that yerin was your step older sister.. he was afraid you would hate him..
