Honestly, I don’t think you can measure someone’s mental age just by how long they’ve lived alone. It’s more about the kind of life they’re living and the stuff they’ve been through.
For any time regressor, they basically come back and live life AGAIN — childhood, teen years, young adulthood, the whole package. So mentally, they’re not actually aging past where they left off in their first life. They’ve never felt what it’s like to be in their 40s, 50s, and so on.
That’s why I think Youngguk’s still stuck in his mid-30s mentally, and he won’t really “be” in his 40s until he actually reaches that age again. It’s like his mental clock just… stopped ticking when he regressed.
So he will be "growing up" together with that girl until both of them reaches his previous age. This is why I never really had a complaint on a regressor's love story. Since if you ignore that youngguk has regressed, they're actually from the same age generation, right? You guys got what I mean?
