Navigating the uncertainty of early adulthood is no easy feat, as Hong Wooree is realizing on his year off from college. Not only is he trying to make it as a published author, but he also thinks that his best friend, Gong Minnee, is a vampire! After making some flawed assumptions, Wooree believes that Minnees secretive behavior comes from hiding his "true" identity-- hes completely unaware that Minnee isnt actually a vampire, and just has a huge crush on him. While Wooree struggles to get his writing published and protect Minnees "secret," Minnee must find a way to confess his feelings for the oblivious Wooree. Will these two be able to reconcile their misunderstandings and allow for a real relationship to blossom?
