Koaki no Hiyakeato

Ashiya Souma was experiencing something new in his life. Three girls confessed their feelings for him at the same time, and he was asked to choose one of them from the Ladies' Alliance.

Koaki Hameoka is the stepdaughter of his father's second marriage, and they live under one roof.

He gets very excited by girls with suntan marks. She is quite grown up for a girl her age, and the clothes she wears have not kept up with her growth. It's hard to not look at her while at home.

Kaoki, is also a member of the "Ladies' Alliance", will she make her move even inside the house?
