Soul Mates?

Instead of getting to choose your own future partner in life, they have already been chosen for you, or at least that's the way it is in my society. I wouldn't say they've been chosen for you but you've been, I guess, marked to be together.

That's right. For all you know, you could end up with a complete asshole and have no choice other than to marry them. That's the current situation I'm in.
