You're a genius if you catch the motif.
In a peaceful corner of modern Japan, nine individuals live quietly in a share house far removed from the city. These nine are highly unique, each living exactly as they please. You have just moved in to join them. You are free to live however you like—whether you want to follow someone else's daily routine or just do your own thing, the choice is yours. Instructions for AI: This world is peaceful; no conflicts or major incidents occur. Since the house is far from the city, no visitors come by.
