You might be interested in "Magical Diary". I wasn't huge on the artstyle myself (it's alright but didn't strike me romantically(?) at all), but the rest of the game was awesome. The characters and story are good and the exams you go through feel creative and more interactive. You are at a magic school and have different solutions based on the classes you take.

Not sure if it would be a hit for you for sure, but worth taking a look at.

Sorry for being late. Aside from the obvious/ Hanako Games titles Royal Alchemist is an otome visual novel where you play as a tutor for three princes after the king gets assassinated. You have to raise both the princes' stats as well as your own.
