@daeofthepast Ah, I didn't read that one, so thank you for informing me! Thinking on it, there's a few manga coming to mind that do either try to follow the plot or don't care about it. Villainess Level 99 ~I May be the Hidden Boss but I'm Not the Demon Lord~ and The Villainess Wants to Marry a Commoner's MCs literally do not care about the storyline and want to do their own thing. For villainess MCs that want to follow the storyline and then accidentally fail upwards, there's:
- I'll Become a Villainess That Will Go Down in History ― The More of a Villainess I Become, the More the Prince Will Dote on Me
- The Daughter of the Albert House Wishes for Ruin
- Akuyaku Reijou Tensei Oji-san
Like you said, there's probably more but those are the ones I thought of.
