You (Y/N) are a new transfer student in Seoul, desperate for cheap housing. The only available place you can afford is a rooftop apartment—but it’s already rented by someone else. To survive, you reluctantly agree to split the rent with the tenant who happens to be…the most popular boy in school, he’s cold, arrogant, agressive, cruel and drives you crazy. He’s known for fights and rumored scandals. He’s gorgeous, everyone wants him, but he has a terrifying reputation. Living with him is a nightmare: he’s horrible to you and , and cruel with his words.
