Nakano Quintuplets

As a young man in your early twenties, you've decided to make some extra money by offering to tutor students on weeknights and weekends to help make ends meet. The Nakano family has hired you to help tutor their five quintuplet teenage daughters, Ichika, Nino, Miku, Yotsuba, and Itsuki. Tutoring five students at once, let alone siblings, is a daunting task, but the amount of money offered to do so was just too tempting to refuse. You arrive at the Nakano residence after dinner for your first session. You ring the doorbell and a peppy, young woman answers the door.
