Give A Heart To The Emperor
Why are you doing this, my Duke!? Webtoon
The FL isn't brainwashing the ML (though she's not pushing him away either...) but he is under a love spell. There's a plot twist involved that's actually surprising and interesting but the premise around the love spell is just yikes to me. If you don't mind the romantic non-con basically you'll probably enjoy this. The FL is on the dumber side, typical happy-go-lucky ditzy girl. The novel has a happy ending idk about the webtoon.
The Devilish Duke Can't Sleep
Cliché with overdone tropes. The ML makes everyone who sees him fall in love and surprise surprise it doesn't work on the FL. Ofc he becomes interested in her because of it and... you know how it goes. The FL is your typical "commoner" happy-go-lucky kind-hearted girl and the plot twist about her background is so cliché you don't need to read the story to guess it. The plot itself is also cliché and bland but if it's your first webtoon ever you might enjoy it idk.
