Hmm, maybe one of these?
Bride's Revenge (sort of an alternate universe sequel with much of the same cast of Maid's Revenge, but a happier ending. The ML is very evil and constantly harms the FL, she in turn plots his eventual downfall. SML, who is the ML of Maid's Revenge, is the good character/love interest.)
More and More Loves You (super toxic ML who blames/torments the FL. I wouldn't call the FL smart or not innocent but the ML is very much like Circle of Love)
Dangerous Love (FL hates the ML at first and even tries to kill him. He's a bit rough but doesn't try to kill her.)
My Villain Husband (ML hates FL, FL hates ML. FL is smart and strong.)
Cheng Xi's Song (villainous ML who holds the FL prisoner, very smart FL)
Please Don’t Spoil Me (enemies to lovers set up.)
Heart Medicine (ML is the double/possibly reincarnation of someone who betrayed/murdered the FL so she hates him/distrusts him. He doesn't try to harm her in his current life, but he did in the past.)
Goodbye Mr. Shao (a lot like Circle of Love - the ML is toxic and keeps the FL prisoner in his house. It's sort of mutual hated - he thinks she killed his sister, she hates him because of how he treats her. It's still airing atm so idk how it will end up,)
I Want to Live to the Finale (ML is the villain, FL tries to take him down. I don't think he ever tries to kill her, but the concept is similar and it's Republican Era setting.)
The Killer Is Also Romantic (kind of lovers to enemies to lovers set up - they're assassins on opposite sides. There's an epic scene where they both try to kill each other and then have the most intense make-out I've seen in a cdrama, lol)
In the Day We Flipped (ML is the enemy of the woman the FL transmigrates into the body of, so he tries to kill her/hates her at first.)
Night of Love With You (kind of? ML is the villain of the story, FL is more annoyed by him at first then viewing him as an enemy. Smart and strong FL.)
Half Awake: Under the Mask (maybe? very toxic, very possessive ML.)
