Another small idea — what if there was a supermarket location in the game with two modes:
🌞 Daytime: normal stuff like snacks, drinks, casual clothes.
🌙 Nighttime: secret fetish shop with sexy outfits, special cards (poses, acts), or items that unlock unique reactions and scenes.
You could also let players buy favorite things for certain girls (like sweets for Koneko), and depending on that, their attitude toward the MC could change — sweeter, more flirty, or teasing.
It’s just a future idea, nothing urgent — but it could make the game feel more interactive and “alive”.
