Really nice game. Took me a while but I managed to achieve first on the trial of mind!
The main gameplay inspiration came from an old game called "True Love" (True Love 95). It is much simpler, shorter, and doesn't have an overarching plot aside from "need to get a girl", but it has basically the same gameplay loop. You can give it a try, but be warned, it is a 30yo game.
Though not really the same, you can also look into Princess Maker 2, another old classic with day-to-day activity management.
