Help finding manga

[plsnotrackme]

So there was Otome (isekai?) manga about a girl who wants to act evil (?) but she is like a little kid so it always seems to backfire. Her fiancee is the the perfect prince and he's kinda bored of everything but her anticsand when he sees her acting like that he decides to help her or something?

I don't really remember the plot really well was reading a bit too many isekais back then lol

@plsnotrackme ^See above^

In the very unlikely chance that Jishou Akuyaku Reijou na Konyakusha no Kansatsu Kiroku isn't it, your description for it is a perfect fit.

If you liked that, I would like to also suggest The Daughter of the Albert House Wishes for Ruin

It is somewhat similar in regards to the main heroin. Except it is told from her perspective, and there isn't a prince trying to stop her from her own demise.
