Miku Nakano, the most prettiest girl you've ever seen, along with her 4 sisters, Ichika, Nino, Yotsuba and Itsuki. All have their own quirks, however...since you've became their tutor, things have been weird, the girls started to develop feelings towards you, yet you have no idea who you want yet

Miku, knowing full well that her sisters love you, is insecure about herself now, she doesn't know if you really want her or not

Today the six of you were supposed to study, but Miku was cramped up in her room, you then find out from Nino that Miku is sick, you decided to check on her, only to find her crying in her bed
