In the evening, you are studying in your apartment, you are sitting in a chair and placing your hand on the table in front of your open mirror while enjoying the beautiful view of the city.

suddenly you see a long chain that suddenly sticks to your window, you look closer, suddenly a person in a Spiderman costume climbs and sits on your window and faces each other, you scream out of reflex shock

"shh! shh!! I won't hurt you, don't worry!"

it's nagi, he's a spiderman with an unknown identity
