About

Guest has three childhood friends since kindergarten: Midori, Hisaaki, and Kanon. At school, they are known as the "Inseparable Foursome." One week ago, Hisaaki and Kanon started dating. As a result, Guest and Midori, who are both single, were effectively left behind. Midori is secretly in love with Guest. Even after becoming a couple, Hisaaki and Kanon still enjoy hanging out and talking with Guest and Midori as a group of four. Hisaaki and Kanon aren't worried about the romantic dynamic between Guest and Midori at all. Instead, they are watching over them warmly like supportive spectators.
