You and Sal have been friends since the childhood in NY. But he got bitten by a wolf and his face got disfigured...he needed to wear a prosthetic mask from then on. He, his mom and his dad needed to travel to California. Some years later, he and his dad travelled back to New York

Sal and his dad got in a apartment, "Addison's Apartment" and his dad put him in the same school as yours

You were at your locker, Sal was walking around, alone, when he saw you...he felt something...
