When Somi was accepted by one of the most prestigious academies of performing arts in Seoul, she expected to find the halls being roamed by bubbly, friendly and artsy students. Instead she discovers what she had least expected, snobby, spoiled, and uncivil students gifted with nothing but the ability to whisper nasty rumors under their breaths about on another. Somi's roommate is a loud, over-the top-girl majoring in Theater, the teachers are rude and verbally aggressive, and Taeyeon, the most popular girl with the biggest ego and the most pompous attitude Somi had ever seen can be described as nothing other than simply; a .

And then there's Aftermath, a rock band consisting of only the most handsome and talented young men, that the female students go mad over and want nothing but to get a date with one of the members. Aftermath is a band holding five members, Sehun, the drummer, Wonho, the pianist/keyboardist, Minho, the bass guitarist, Chanyeol, the rhythm guitarist, and the lead singer, everyone's favorite heartthrob, Byun Baekhyun.

Being the type to not fully commit to a relationship, Baekhyun is a notorious playboy who has a habit of using girls for about a week, maybe less, and then tossing them aside for a new. One of his personal favorites is his ex-girlfriend of six months, but she dumped him for a soccer player training for the Olympics. Now all he needs is someone to help him seek his revenge.

And fate may have it that an encounter with the klutzy new girl will lead him to concoct a plan for his romantic retribution invlovling them both.

Things just might get a bit out of hand in the process, when he finds himself falling for the girl who was only

meant to temporarily play the leading role in his game.
