■■■Story■■■
About 9 minutes walk from the station. The apartment was located up a gentle slope.
A slightly old wooden building. The name of the apartment with a large clock as its landmark is

"Temporary Hall"

It's not just all at once, it's all at once.
It's not just one, it's just one.

I don't know when or who called it, but the name it got was ``Maison Temporary''.

An apartment occupied only by women who are disappointed in the existence of a male sibling.


``Akira Futaba'' was supposed to be the new resident there.
Although he was rejected as a matter of course, his energy and positivity opened the hearts of the girls and he was accepted as an official resident.


On the contrary, the girls, who have completely fallen for Akira, propose that they live as one family through a step-brother-sister relationship.


However, just as a new family life was about to begin, my beloved sister-in-law, who was also my childhood friend, made a declaration.

“I’m quitting my brother’s sister!”


The new sisters, who are not related by blood, want to be number two in the family, and the childhood friend who is supposed to be her younger sister, who wants to be number one.
Are you alone, with your family, or with a harem? Is it okay to be number one, or is it okay to be number two?

A sweet, fun, enviable, but slightly painful real life that unfolds under one roof.

Which kind of relationship are you looking for?
