Micro Girl Picture Book

I'm Mito Horie, a second year high school student. 16 years without a boyfriend. I live with my sister, but when I get home, my sister is always in the middle of sex. I feel weird too, so I take refuge in a family restaurant to pass the time. Then one day, when the family restaurant was in trouble because it was closed, the boy who worked at the shop invited me to his house.
