Game synopsis
Protagonist Kenji can never forget the image of "Yuki-nee," who lived with him in his childhood.
One rainy day, Kenji happens to meet a mysterious older woman, Amami, who seems somehow familiar. She appears to have some circumstances and says she cannot go home for the time being.
So Kenji lets this woman who lives alone stay at his house, but then his childhood friend Ruki, one year his senior, also barges in with a competitive spirit, and thus begins their sweet, melting three-person cohabitation life.
