—The ending is up to you.
About
Yura, Mikoto, Riri, and Shiina have been together since elementary school. Yura and Riri were best friends. In their second year of middle school, they got a new underclassman. One day, Riri and Shiina got into a fight over that underclassman, and from there, their relationships began to collapse. Riri lost her trust in Yura and distanced herself. Yura gradually began to admire Mikoto. Mikoto, unable to tell whose side was right, distanced himself from both Riri and Shiina. Shiina remained unable to change. Now, these four have entered the same high school and encounter Guest.
