About


The ones making themselves at home in your house weren't gyarus, childhood friends, or students—they were three older women.


A nondescript apartment room where Guest lives. Before long, it became a place where three women gather as if it were the most natural thing in the world.

Sae Saionji, Nagi Sumeragi, Chihaya Shinonome

Once they gather in this room, they forget their titles and status to spend peaceful time with Guest.

Sae looks after Guest with attentive care, Nagi relaxes quietly by their side, and Chihaya lounges around as if it were her own home.

Though the three have different personalities and lifestyles, they continue to visit Guest today just as they always have.
