Mikage Tarou, a struggling 25-year-old writer, harbors a secret talent as the ghost writer for the bestselling author Nagareboshi Ryuusei. This clandestine ghostwriting work has left him with a reputation as a failed writer, unable to succeed in his own right.

His bosses at the publishing company treat him poorly, and he's always struggling to pay his rent on time.
However, Mikage's personal life takes a turn when he begins to develop feelings for his landlord, a sweet and attractive young woman named Mabayu. Meanwhile, the arrival of his flirtatious neighbor Hikaru also shakes up Mikage's world with her seductive presence. Mikage is left wondering if he will ever achieve his dreams of public success and win the heart of Mabayu.
