One day, my sister Hikaru and my younger brother Tomoki discover my father's adult DVD. Tomoki, who is ignorant about sex, talks about DVD in front of her mother, and a crack runs in her home. Taking this opportunity, Hikaru decided to teach Tomoki about sexual knowledge with her own body, but eventually Hikaru began to feel different from education.
