Markiplier - Chairfu.

Mark's mentioned he had a girlfriend a few years ago, but unfortunately it was an abusive relationship (this is why Mark's said that he finds it odd how people will be so horrified at "violence against women" in fiction but hardly ever at "violence against men," because he was on the receiving end of an abusive girlfriend).

The main company he keeps are his dogs, one of which he got recently and is so cute.
