That day, the protagonist, Takimura Hiroshi, hung his head and felt dejected on a bench at the park in the evening. A place to live... gone.

According to his apartment's contract, in case that the rent couldn't be withdrawal​ from his account, he would have to leave immediately. As a result, his luggage was taken outside, and the lock for the front door was changed to another one. According to the realtor, if he was there at the time his luggage was taken out, it could have been different.

Job hunting failed, and no place to live as well... What will happen from now on?

"If that's the case, then why don't you come to our house?"

While thinking and sighing for a while, a voice called out to him. The three women told him that they live together nearby, and after hearing about his depressed situation, the women invited him. Instead of receiving rent, they want him to do household chores and, maybe, give him a few shifts as a part-time job.

Takimura bowed his head and gladly accepted their offer. Thus begins the domestic life of 4 people.
