Chad:
Came in on the reality TV wave of 'the bachelor'. That's his thing.
1st he liked Marissa (but she kinda went with Jordan)
Then he liked Amelia (but she kinda went with Sam)
So he ended up with Sarah.
Sarah gets drunk and talks to him like dirt. And he takes it. Why?
Either because he is weak. Or because he using her as the reality TV meal ticket for the duration of the show, so he rides it out.
Either way, it's all BS.
Aside from that, who is he?
A man who likes mince? We know nothing else about him.
