JK Sakura-chan no Enmusubi

Having been raised by her Mother and attending an all-girls' school, Sakura's knowledge of men was understandably minimal. Invited by her friends to try out a "dating" site, she had the good fortune of encountering a man who not only recognized her lack of knowledge, but wanted to keep her safe, and so they started dating for real. After their first time having sex, Sakura discovered a whole new reason to pursue her dream of becoming a housewife!
