Mikage Tarou is a 25-year-old writer living in poverty with a secret: he is the ghostwriter for Nagareboshi Ryuusei, an author who has recently achieved wild popularity. Because Tarou's ghostwriting work is strictly confidential, everyone he knows considers him something of a failure. His personal life does not appear very successful either, as he lacks a prestigious education and has never slept with a woman. His publishing company treats him with little respect, and he is always behind on his apartment rent. However, his personal life has become more interesting lately. He has a crush on his landlord, an innocent and pretty young woman named Mabayu, while his sexy, uninhibited neighbor Hikaru keeps causing all sorts of awkward situations. Will Mikage ever attain any kind of public success, and will he ever end up with Mabayu?
