I have two suggestions.
The first comes from the fact that I've seen some people commenting that the progression doesn't seem very natural in the game regarding Anna. I think it would be cool if, after groping her in the kitchen, there was an option to kiss her, before reaching 5 hearts. I think more kissing options in general with Anna would be good; kisses in the park, on the beach, and some other places would be interesting, not just groping. (I know that in the love route there's the make-out option; I'm talking about options like that, but in more situations.)
My second suggestion is that I think it would be cool to have a scene with Anna sleeping, either in her room or in the living room. The scene would start with her sleeping and then waking up, similar to what she does with the MC on Wednesdays.
As always, thank you guys for the amazing game
