Taichi Miyakura was a student who had been living alone because both of his parents were busy working for a company,

One day, his mother Fuuko suddenly quitted the company due to his entrance exam and became a housewife.

However, because she was quite workaholic, she couldn't handle the housework at all.

The days with the extremely clumsy and vulnerable Fuuko begin.

Although Taichi's sexual impulses were gradually getting out of control, he could still resist them, barely.

However, someone suddenly tumbled into their everyday life...?

Fuuko: "It's okay, there are still rooms left over... but because you are living here... you have to take care of Taichi..."

Mao: "Y...Yes... I will do my best! There is nowhere else I can go."

Taichi: "Don't worry about that! You don't have to do it! I can take care of myself!"
