A secret turns into a friendship that can withstand any test, no matter how tough. When the rebellious Jae-hee and the aloof Heung-soo meet for the first time at university, they could hardly be more different: While Jae-hee stumbles from one problem to the next due to her provocative nature, Heung-soo hides his homosexuality and doesn't let anyone get close to him. But when Jae-hee accidentally finds out about his secret, an unexpected relationship develops between them. The rest of the world thinks they're the perfect couple - instead, they roam the clubs of Seoul together as best friends, navigating the ups and downs of love, friendship and social expectations. A life full of opportunities lies ahead of them, but also full of obstacles and prejudices that they must overcome in order to find themselves.
