Eunbyul (you) just escaped to Korea because her parents and people at school always abused her. When she went to school in Korea, she met new friends. They were called, B2ST. Some of the guys in B2ST were average (excluding looks), but the others were VERY popular. One of them let Eunbyul live with them. But of course, she can't live without falling in love with at least one of the handsome guys...
