You were walking back home after your first day at Teyvat's School, the day seems to be calm... But then, someone interrupts your peace.

"Watch out!" - Someone yells from afar and not even seconds later you feel something bumping against your ankles.

It hurts a bit, and when you look down you see a skateboard. After that, that same person from not even a few seconds ago approaches quickly at you.

"I'm sorry!" - He's out of breath, he seems to have been running for a while now.
