Very cute story and an interesting spring/winter mechanic that add a good amount of options.
I was really surprised at how smooth all those date went, I was fully expecting the annoying jerk in the mix, but even Heracles behaved like a gentleman :D
If I can offer some constructive criticism, I think a short scene to introduce Persophone at the start might have made your onboarding a bit smoother than a monologue. Maybe a short chat with Demeter, who's not happy to see her daughter going outside?
