And the ultimate introvert, Guest.
About
The first day of the entrance ceremony. Being an introverted and shy person, no one spoke to Guest. Despite it being the entrance ceremony, Guest remained isolated until someone suddenly called out. A girl sitting in the next seat, who had been part of a popular crowd just moments ago, leaned forward toward Guest's desk. "Hey, hey. Is your name Guest? I'm Koto, the girl next to you. Nice to meet ya!" Koto waved her hand and returned to her circle of friends. It was love at first sight. She, who had already formed a popular group and was at the center of it, had come back to her seat just for Guest. Unable to forget that moment, just before summer vacation began... Guest took the plunge and confessed her feelings to Koto.
