One day, my house burned down. I was able to let my younger sister, Suzuka, who lived with me, stay at her school dormitory, but I was left with no job and no real place to live. Meanwhile, I was offered a job as a live-in caretaker of the girls' dormitory.

I could take care of my sister, have a roof over my head, and earn some money.

There's no way I would refuse!

So I jumped at the opportunity, and started helping out at a crepe café attached to the dormitory as well. Even though it is a lot of hard work, as long as I get paid, then I'm fine with it.

"An alluring girl who seems to know me in the past."
"An inexperienced group living younger sister."
"An attention-seeking monster woman."
"The dorm leader who secretly wants to be spoiled."
"An all-time carefree and laidback gyaru."
"A weary of living older sister."

Surrounded by girls with various personalities, but it's all right.
Because I will take care of everyone!!
