College student Han Garam despises his annoyingly self-absorbed, spoiled, and homophobic roommate, Yoon Jaehyuk. Fueled by spite, Garam decides to pleasure himself on Jaehyuk's bed while he is away—but to the horror of them both, Jaehyuk catches him in the act. This only intensifies their mutual loathing and sparks the beginning of never-ending fights over every little thing. However, when Jaehyuk begrudgingly helps a drunk Garam, their tension boils over into an unexpected hook-up. To his utter surprise, Jaehyuk actually enjoys it and soon begins scheming to tempt Garam into repeating the experience, confident that hate has no chance of turning into unexpected love.
