Trauma is about you forgetting your most important bestfriend that was with you for as long as you can remember. You are a collage student who is also the daughter of JYP Entertainment, not just that you are the best hairstylist of a handsome boy group you work with. But before you became their hairstylist something tragic has happened to you in the past and that was how you became an isolated, quiet person. But as you keep working with the band, you started to open up little by little.
