The Hot Blooded Friend

When Sain was a little kid without much to do at home, he would take walks around the town. He would hang out at the local park and make snowballs, but one day, he encountered one of the coolest (at the time) kids. A kid pretending to be a wrestler, or luchadore (Sain doesn't recall), just standing and saying how he doesn't feel cold at all despite only having on summer clothes. Despite the kids shivering, Sain was immensely impressed and later came to know this friend as 'Sot', the wrestling name the kid came up with. They keep contact every so often, but with the incident that caused Sain to leave, he isn't exactly sure what happened to him since that point in time.
(Sot is not a character I've put on this site yet, but maybe one day I will get to him.)
