Ane Yome Quartet 1

As summer begins, Kouki moves in with his beloved Hanabishi sisters—Yurina, Momone, Saori, and Anzu—while their parents are abroad. Each woman, bound to him by childhood affection, now sees him differently—Yurina teasingly lazy, Momone doting endlessly, Saori quietly devoted, Anzu playfully demanding. Their rivalry ignites as seductions escalate, each sister tempting Kouki with fiery passion, longing for him to choose her as his bride. Who will he surrender to as pleasure blurs the lines between family and forbidden desire?
