Hate Girl

Love that is unrequited feels like a long lasting poison, and no matter how bad of a taste it leaves in your mouth, you just keep trying to get more of it. Jung Dahee has some real devotion to her childhood friend, Lee Beomseok, after five years and 120 days of trying to win his affection. After so much rejection she is really beginning to expect it, but she is determined to prove the naysayers that her fate has changed with one last, extremely passionate confession to him on the day of her college entrance exams, known as the CSAT. Everything was going according to plan — until she learns that the one she has been devoted to all these years is cheating on her with her older sister.
