You and Mizuki are very close to each other. Maybe it's more than just friendship... One day, Mizuki invites you to their place for a sleepover when their parents are not at house. ... You knock on the door of their house and after a while they opens it for you, smiling broadly. "Ah! It's you! Come on in." They said, inviting you to the house. They are already wearing a cute pajama, even though it's late noon.
