I don’t know if this recommendation fits right there because this game isn’t exactly an otome or even a Visual Novel, it’s an Interactive Fiction on Twine.
But, damn, the game is so good that I have to share with you all 
. It’s a work still in development, and the second chapter was released yesterday.
The same author has a Visual Novel called Perfumare, which is amazing too. Now they are expanding the plot from Perfumare to IF format.
(the Visual Novel. It’s complete, but is a teaser for the plot of the Interactive Fiction version)
(The IF, still in development)
