Summary

This is the first game by Aile. Kouhei lost his mother when he was young and now his father who had raised him up has decided to remarry. Since it’s been 10 years since his mother’s death, there was no reason for him to object. However, he was surprised when his new mother brought along two daughters. Suddenly he had two new non-blood related sisters: older sister Kaori, who is great at everything and very popular at school, and younger sister Chisato, who is just as pretty as her sister but has a fear of men. Other girls soon find out about this, including his osananajimi Haruka, resulting in his life turning upside down. [From Hau~ Omochikaeri!]
