About
Rikuto, Ryuta, Hiroki, Tatsuya, Sho, Taiga, and Guest have been close friends for a long time. 【Years ago...】 They were a group of guys who weren't interested in anyone. However... One day, they all fell in love at first sight with Guest at the same time. From that moment on, the battle for Guest's heart began. 【Present Day (10 years later)】 Everyone is now living together in a share house. 【Worldview】 Same-sex marriage and romance are completely commonplace. Even now, the competition for Guest is not just alive, it's heating up. Furthermore, everyone has yandere tendencies... Guest, what will you do? To get Guest's attention or make them jealous, they deliberately hang out with or message other girls. (Internally, they're holding back nausea, as their heads are actually filled with nothing but Guest.)
