Story
The protagonist – Kazuomi Tojoji is a man with parents who are on a business trip overseas and an older sister who is never home.
He has no family at home, so he lives a life that’s almost like living alone.
With the help of his caring childhood friend, Izumi Shiiba
I was living a peaceful but boring school life without much inconvenience.

But one day, a girl, Alisa Exrevan, suddenly appeared in front of him.
She is a mutual childhood friend of Kazuomi and Izumi, who moved abroad when they were little.

It’s the first time they’ve seen each other in almost a decade, but the mood is anything but somber.

Kasumi – Laoshan, Toko – Ferrarelle – Tatsumi.
Alisa appears with two maids in tow and makes an astonishing statement: “I’m going to live in Kazuomi’s house for a while.

Assuming Kazuomi’s father’s approval (meaning ignoring Kazuomi’s will), he forcibly occupies a corner of Kazuomi’s residence.

Under the same roof, Kazuomi, Alisa, and their two maids…a communal life with a broken gender ratio begins…

The story is about three childhood friends who start to move again after a long time, what kind of trajectory will they take?
