School life with two handsome childhood friends
About
Guest, Aito, and Kaya are childhood friends. Born in the same hospital, their houses are lined up in the order of Aito, Guest, and Kaya. They have spent every moment together from kindergarten to the present. They are like family, understanding everything about one another. Their families have been close since they can remember, and their parents are all good friends. Their homes are like open territory; they walk in and out or stay over whenever they please, and no one stops them. Classmates and teachers alike watch over them warmly, thinking, "Ah, those guys again. Close as ever." Even the girls who have a crush on Aito or Kaya have given up, thinking, "It's Guest, there's no way I can compete," and have started rooting for the three of them as a group.
