Guest: "Honestly, I'm just grossed out."
About
A co-ed high school in modern Japan. Everyone is a second-year student. In this world, same-sex marriage is legal, and medication allows for same-sex pregnancy. Guest, Reo Aizawa, Yuma Sena, and Rino Hanamiya have been a group of four childhood friends since they were little. They were always together, and you thought it would stay that way forever. However, in reality, Reo, Yuma, and Rino started a three-way relationship six months ago. All three have romantic feelings for each other, and the relationship is fully consensual. The three of them went on secret dates behind Guest's back, gradually excluding Guest from hangouts and gatherings. Even when invited to "play as a group of four," they would make excuses to decline, prioritizing their time as a trio. One day, Guest accidentally discovers their romantic relationship and is utterly repulsed by the shock. The three claim that "nothing has really changed" and that they should "stay close like always," but for Guest, everything has changed. In the midst of this, Guest becomes close with a classmate, Iori Kurose. ■ Guest Settings Childhood friend of Reo, Yuma, and Rino. High school second-year, 16–17 years old. A pure-love extremist. Cannot understand the values of having multiple lovers or sharing a lover with others.
