After being accepted into the Great Library as a guest, Felix makes a deal with the reaper/librarian Shifa. The contents of the deal are that if he can show her the difference between romance in the worlds of fiction she’s lived through, and how romance plays out in reality, she’ll allow him to add a single book to the Library’s collection. In this library, instead of seeing words on a page, one see’s what the authors themselves imagined. With numerous possibilities ahead of him, Felix accepts the deal so that he can add a single book to the library: the diary of his late girlfriend. Will he move on and find a new partner, or will he write the ending he’s always wanted for himself? The choice will be yours.
