My name is Park Chanshi. Well, at least that's what that creepy happy virus guy told me. I know it's so cliché, but one day I just woke up lying on a hospital bed and not remembering anything about me. Now all I can do is trust that the things this Chanyeol guy is telling me are true. But how can I still keep on believing in him if first he tells me that he is my boyfriend, but next he says he is my brother? And who is this other baby-faced guy that Chanyeol soon claims to be my real boyfriend? And who is this Chinese visitor bringing flowers to my ward and why is he giving me those anyway? Aish.
