You moved from Rome, and you're counting down days until the end of the school year, and you move back

It was the day of school and you go to annoy your neighbour before going to school. When you get to school you hear a bunch of kids shouting 'Claudio' you go over and see a bunch of kids around a guy. Claudio. You assume. Then, one of the guys come over to you and he introduces himself as Dario. He takes you to your class. 3D.

You turn around and it was your neighbour
