I like where the game is going: you chase bad guy, bad guy create waifus, waifus have bad time, you save waifu, you have good time, the circle repeat.
However, i felt like the game is lacking something. It felt a bit... Too casual, and i want it to have some spices, for a quality porn game, of course.
Collector room: i have a bunch of weird fossils, some shiny stones and random rarities. Isn't it cool if i can place things inside my house for trophies, and create extra events for my waifus (memories/ robbery event / money vault to flex / etc...) i want my Gardevoir to swim in money for a chance.
Costume systems:
I have a bunch of junks, steel, stone, gems, etcs... How about we use such thing to create custom costumes then? Why play it fair and casual when you can have a fox in maid costume, a poison fairy in full steel armor, or a water dog in drip suit? We have materials, we have money, and why not funny costumes?
Cooking minigames:
What really absurd that we have a kitchen but no cooking minigames. We have all kind of berries, we catch fishes, we slap pokemons, then why can't we cook? Who care that is just random hp potion in disguise? I want to eat and i will feed my girls well. A radiant quest system where you can search for ingredients to make food, hell, to sell your food, is nice. I want cake! And food as gift is nice...
For waifumon relationship system, i think a mix of events + gifts and relationship choices chat is a good balance.
