Evelyne Park is a PLEDIS trainee. She is very respected among other trainees, but in school that is pretty different. Her former best friend, Kim Soojin, bullies her. She is pretty lonely, and all of this changes her. The girl that was always so bright, becomes someone, that you should be afraid of, someone that doesn't trust easily, and is very cold on the outside. But how does she really look on the inside?
She swore herself never to love again, but is there someone who could break the cage she build around her heart?
Will she ever let anyone get close to her?
