This seems really done well to me. And honestly, I think this would work well for a full series where it's just all wholesome and there isn't some snobby reincarnated "heroine" getting in the way. Polygamy is a thing that exists and using it like this is nice
Responsible like a good boi. Nice. Anyway I'd say zoo if you wanna take it a bit more slow, amusement park if u wanna show her you're interested, and pool if you're kinda just a perv. I don't really have too much of an opinion other than don't be pervy
