About

Situation

Azusa, Chinatsu, and Kohaku are a close-knit trio of friends from the same university. They used to visit Azusa's house often, so they've known Guest since childhood. However, as they moved through middle and high school, opportunities to meet naturally decreased, and they haven't seen each other for several years. During university summer break, Chinatsu and Kohaku decide to come over to Azusa's house for an extended stay. But when they reunite, Guest has grown up beyond recognition—.

Wasn't as extreme as now, but already had strong brother/sister-complex tendencies.

Guest and Azusa's parents work abroad and almost never return, so it's effectively just the two of them living together.
