Cheese in the Trap

Having returned to college after a year long break due to her family's poor background, Hong Seol, a hardworking over-achiever, inadvertently gets on the wrong side of her senior, Yoo Jung, who's athletic, good looking, gets good grades and has a kind personality, as well as a hidden dark side. From then on her life takes a turn for the worse and Hong Seol is almost certain it's all Yoo Jung's doing. So why is he suddenly acting so friendly a year later?
