Kim Jongdae is an average college student. He's in his early twenties, struggling to find a girlfriend, working at a convenience store for extra cash, and aiming to be a doctor. He's all around a nice guy. What he doesn't want you to know is that he has a family. A family full of werewolves. A mom. A dad. And Kim Jongin. His little brother. The little brother Jongdae hates. So when Jongin has to move in with Jongdae, they both struggle to get along and accept one another. With time, they run into strange friends, enemies, and maybe, just maybe, learn to love a brother.
