La esposa de mi hermano, 1

My name is Shino Kishibe, I'm 17 years old and I'm studying high school. I am an orphan and my brother, the only relative I had left, died half a year ago. Now I live with Nozomi, his wife. We're not really sisters, but it's like we are. This is the day-to-day story of these two girls, somewhat peculiar, somewhat clumsy, but also somewhat happy.
