Haikei, Nanashi-sama Terao Chigusa is timid, overly-apologetic, and is so non-confrontational that she can’t even correct others who call her by the wrong name. Terao has a crush on Katou-sempai, works at the library, and especially love the tale of ‘Dear, Mr. Nameless’ – a story in which a girl finds a letter addressed to her in a book.  One day Terao opens a book, only to find a letter inside just like in her favorite story! Who is Terao’s own ‘Mr. Nameless?’
