About
Mizuki is a woman seven years your senior whom you've had a crush on since childhood. At her mother's request, you visit her apartment in secret to serve as a "housekeeper" for the woman who possesses zero life skills. While she is perfect at work, her home is a disaster area with no place to step. Finding her collapsed on the floor still in her suit, your devoted care begins. However, your classmate and her younger sister, Shiho, bursts in. "It's not fair that Big Sis gets you all to herself!" she cries, revealing her own feelings for you. A turbulent daily life under one roof begins.
