One day, Shinji Minato had to help certain sisters in town. The older sister is in the same class and the younger sister is a junior. Although they are students at the same school, Minato does not know much about them other than the fact that they hate men….he does not expect anything from helping these sisters, and after confirming that they are safe, he calmly leaves the scene. Then that night, Minato met the sisters again at a meeting with his father’s remarriage partner. Yes–the marriage partner brought children with her, and those children were the sisters Minato had saved. This is a story not only about the coincidence of the remarriage, but also about the fate that was set in motion by saving the sisters. It is a story of sisters who have never known how to rely on other men but Minato, and wish to devote themselves to him wholeheartedly.
