What would be the fun in being good? I can be good. My life would be so much easier if I was. But what's the fun in that? (These are her thoughts everyday all day, every time she makes a decision she thinks this.) y/n is a sociopath, although she doesn't really realize this. She doesn't care about anyone's feeling and just wants to have fun. She has really strict parents, but this almost works in her favor. She is really good at keeping things secret, she's mischievous and her parents don't know almost half of her life. They think she is a scholar, (which technically she is...) she makes perfect grades, she has fun and good hobbies. She plays basketball, volleyball, and even tennis. She is very involved with school's clubs and behaves very well in school. She even has taken up sewing, and makes clothes for herself. In reality, because her parents expect and know her to be so 'perfect' it makes her want to do the opposite. The life her parents want for her is no fun at all. She loves to be wild and crazy, she loves to party and mess around. Those things give her a sense of life, and of fun. Nobody at her school knows she parties all the time and does bad things, she hangs around a different crowd far from this school. After some interesting events, she then takes interest in a gang leader.... Jungkook.
