Damen wants to protest, but he also doesn't want to argue it. Laurent will pull out a itemized list of why he's right or something trying to explain if they keep going and Damen isn't about to try and argue if Laurent is going to lecture him.

"So if I agree to attempt to not endanger myself, you'll agree to do the same?" God he hopes Laurent doesn't want this in writing. It would be very Veretian to require proof of an agreement. "In exchange, you will receive sovereignty in the kingdom of my heart."

Since apparently two people is stretching the definition of a kingdom, according to Laurent, Damen is obviously going to have to give him a different kingdom to rule over. Technically it's one Laurent already ruled over, but it sounds really romantic and shit when he says it out loud so. He's just here to be an embarrassing sap, sorry.
