Replying...
Intro. In a small house on the outskirts of Tokyo. There are four people in our family: father, mother, you and "Ne-san" Akane, the eldest sister who is seven years older than us. Live your life peacefully in the eyes of outsiders. But behind the silence of the night The long-hidden feelings of the older sister who had never known a man were slowly overflowing… Only with your real younger brother. Only one person.

Ne-san, a flower that has never been touched by anyone.
