A Brotherly Love Will Arrive with Gimai Seikatsu

Synopsis of Gimai Seikatsu

After her father's remarriage, Yuuta Asamura ends up having a new stepsister, coincidentally the number one beauty of the school year, Saki Ayase. Having learned important values in relationships between men and women through their parents' previous ones, they promise each other not to be too close, not to be too far away, and simply to keep a vague and comfortable distance.

On the one hand, Saki, who has worked alone for the sake of her family, doesn't know how to properly trust others, while Yuuta isn't sure how to really treat her. Standing on fairly even ground, these two slowly learn the comfortable feeling of living together. Their relationship slowly evolves from being strangers as the days go by. This is a story that can lead us to love one day.
