Minami is a 27-year-old female office worker in an advertisement agency. Though she has a boyfriend, she spends the majority of her time working and appears to feel ambivalent about the relationship at best. When the boyfriend finally breaks up with her, it's the push she needs to start a social life with her co-workers. In-office romances soon follow. Much of the story is told through Minami's thoughts, which are full of self-doubt.
