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!!
