Sangsang University. There are two campus belles attending this school. One is Kang Seulgi, a freshman in the Applied Music department, and the other is her senior, Park Siyoung. Before Kang Seulgi entered the university, Park Siyoung received all the attention and favor from men. She reigned as the perfect Queen Bee of the university, keeping men under her thumb and enjoying a very comfortable college life. However, a year later, as Park Siyoung became a sophomore, the beautiful freshman Kang Seulgi entered her department and drew everyone's gaze. Feeling her solid position waver, Park Siyoung began to persistently bully Kang Seulgi out of immense jealousy and anger to break her down.

Thus, Park Siyoung's ridiculous false rumors began to spread through the university, and those rumors shattered her mental state. For her, every single day was precarious and fearful. Within the university, there was no place for her to lean on or stay for long. Everyone in the university except herself believed the rumors attached to her; women mocked her, and men approached her with impure intentions. That image, once branded, could not be washed away. The daily creative and cruel bullying tore her heart miserably and began to slowly destroy her.
