Just found another completed manwha which looks good. It's I Became a Duke's Maid.

Time to binge another good manwha ~

Intending to read The Reason Why Raeliana Ended up at the Duke's Mansion and found this when I typed "Duke man" in the search bar. Will come back here after I finish the other one first.

I'm more of a novel reader, so I'm not that well informed about "good" manwha. I simply searched for completed manwha to read. I'm just going to list those I remember or just recently read:
-The Villainess Reverses the Hourglass-Who Made Me a Princess -Marriage of Convenience-Survive as the Hero's Wife-The Duchess' 50 Tea Recipes-My Fair Maid (Currently reading on another site cuz this site doesn't have it)-The Reason Why Raeliana Ended Up At The Duke's Mansion ( Watched the anime a while a go and planning to read after finishing the one above)-The Baby Isn't Yours (Also planning to read)
Hope that helps.

The magic of Manga Katana. I searched for My Fair Maid but this show up as one of the search results.

This is finished please upload the remaining 10 chapters.

Clarence be like: you thought you captured me. But it was me, who captured you!

So what happened to the scum?

Big talk for a trash

Some heads will be rolling today

Seems like it'll really be Kenneth route huh

Lol

Dale x Kenneth is going strong XD

Hoho~

Please go the harem route!

Papa doesn't approve of this ship! (⁠눈⁠‸⁠눈⁠)

Just realized but if she becomes the head of the Duchy, she and the crown prince can't be together. Their position will not allow them to be together. Unless either of them throw away their position which is impossible. Clarence maybe, if she can somehow manage to give her position to Clive.

Urgh.... I really want to rip out his heart and choke him with it.

Make grandpa proud T^T

Husbando alliance!
