"A brief and ephemeral life, felt like it......"

Hit by a sudden rain at night, Gouda walks into a park that he does not usually pass as a shortcut. He has to work overtime everyday, so he always returns home late at night. Even though he wants to change job, he does not have enough achievement or qualifications to do so. In addition to being soaking wet, he just want to rest as soon as possible. It is at this time that he meets a runaway girl Kamae Mitsumi. Unwillingly, he takes her in for one night. However, he later lets her stay with him―― Thus, a peculiar cohabitation life begins.
