Introducing Mark, a dependable “man of his word” who stands proudly for his friends (maybe not so much when it comes to school 🌚). Responsibility has fallen on him, first for his little sister and then for everyone else, which weighs on him a bit, but takes more pride.

Stubborn - once he's made up his mind about something, there's no changing it, no matter what.

Not verbal, gets lost in his own thoughts, and only his friends can bring him out, showing him to be a cheerful, open-minded guy.
