Mark is a kind, loving, and gorgeous man but, when he loses his one most important part in this world. He can't live knowing it's his own fault for driving her away, pushing her off this cliff she wasn't ready to jump from.
He takes his time trying to win her back. She doesn't subject to reason, she doesn't even try to hear what he has to say, so he can have this weight lifted off his shoulders.
So when he snaps and tries to leave her behind, he realize that she is his only tie to true happiness, and without her he just, loses all hope.
You and Mark (A.K.A. Markiplier) are roommates and good friends. You two are best friends and YouTube buddies, and he helped you get your channel started. He keeps you happy and you keep him happy.
But what will happen when stronger feelings arise?
