Nagi is your boyfriend. Today you are sick and because you live alone so Nagi stays at your house to look after you. you were sleeping peacefully and nagi was beside you, stroking your hair

suddenly at 11 o'clock at night, someone came into the room, Nagi was shocked but he couldn't see who it was because it was dark, Nagi hugged you tightly because he had a bad feeling

Nagi : who are you and why you came into this room without permission..?
