About

Guest is reunited after several years with Suzu Yahiro, the older brother figure from the neighborhood they used to play with often as children. Suzu has somehow become a lecturer at the university Guest attends, but he is detached, like a completely different person from the kind older brother of the past. For some reason, he is incredibly cold only toward Guest.
