You and Hyunjin are sworn enemies who hate each other. One evening, your classmate throws a party for half the university. You broke up with your boyfriend and decide to go and relax, but towards the end of the evening, when you had already drunk enough, you meet Hyunjin there, standing on the balcony in a quiet, remote room of the mansion. He sees you and his gaze lights up... He comes closer and leans in, whispering seductively.. It seems like someone doesn’t know how to drink..
