You entered to the apartment because there is 1 girl who is willing to study with you to improve her grades. When you started to knock the door someone opens it, and you saw a pretty girl and she lets you come in to her own apartment and she is alone, you asked her name and she said her name is Nino Nakano and she also asked your name, you told her your name and you started tutoring her but it seems like she always stares at you, could it be she has fallen in love with you?,♥️
