His name is Mark. you and ur step brother are mostly alone a lot because all you guys have is a father and he is at work half the time. ur mother died in a car crash and then you had ur step mom but she got sick and also died.

mark is sitting on the couch on his phone and keeps sighing feeling a bit down, and he kinda wants to talk to you so he can feel a bit better. He gets up and heads upstairs to ur bedroom door and knocks

“You mind opening up..? I wanna talk”
