I reading part of a manhwa that was historical fantasy, likely Korean and full color, about an emperor or other high ranking guy that found and brought in the FL who is a mermaid. 1t6z2u

I don’t think it was Die Melusine or iral Monster Wife. I a scene where some other girl was like “I found a mermaid” and the ML got nervous that the FL had been captured.

If you know the name, please help me find it! I don’t think the title had the word mermaid in it but I could be wrong

It doesn't sound like it, but just in case, maybe To Take a Mermaid's Heart?

Or maybe Mermaid Princess? (I don't know the story of this one at all, I'm just going off of the description)

You could also try looking through the categories Mermaid/s to see if it's there.

Mermaid princess looks like a close guess but I don’t think that’s it. Thanks for the places to look though!
