I also crave non-dumb MCs. Some I recommend but the plots are not that similar to this:
How to Get My Husband on My Side
I Became the Male Lead's Adopted Daughter
How to Be a Dark Hero's Daughter
The One Within the Villainess
The Broken Ring : This Marriage Will Fail Anyway
Second Life of a Trash Princess
Men of the Harem
I'll Be The Matriarch In This Life / I shall master this family
The Princess Imprints a Traitor
I Raised an Obsessive Servant / My Ray of Hope
Say Ah, the Golden Spoon is Entering
The Villainess is a Marionette
It's not the same, but you can try the following, if haven't read it yet:
24 Hours Resurrection of the Villainess {EMINENCE},
Death Is The Only Ending For The Villainess,
I Thought It Was a Common Isekai Story,
Lord Baby Runs A Romance Fantasy With Cash,
A Beast Swallowed by a Flower,
I'm at Chapter 23 and I'm dropping it. I'm actually looking for a quick witted mc, can someone recommend me some.
