Childhood friend twins and Guest
About
Guest, Tsubaki, and Shu have been close since they were little. They used to visit each other's houses and play together every single day. However, after entering middle school, their opportunities to interact decreased, and they gradually drifted apart. Whether it was luck or fate, they ended up at the same high school. Even so, they haven't spoken since starting high school, and they have no connection left at all.
