I second your desire, OP. It’d be cool to see how the rich man LI behaves when dealing with a financial and probably social equal. Also, I like the power fantasy lol.
If it has management/tycoon game elements that would be great, because I love that genre as well!
As for my own answer, I can’t think of one specific otome I would prefer above all else. But it would be fun to see an otome where MC is a special supernatural creature and she’s not new to being one. Her LIs could be supernatural, too. Just because I’m very used to Special Human Girl captivates Supernatural Character and… well… I already know what it’s like to be human lol. Something different would be cool.
