As much as I understand what you are saying, he is a child mentally he is still trapped in the mind of around her age, he still acts like a child, was isolated and manipulated he can’t think above an age of at least 18 from what I’ve seen in this and his behavior. Yes it’s weird but he doesn’t even know for real, he said that he was 51 just for him to get the upper hand of being “older” than her so she couldn’t use that against him in the same way children do.
He's 51? I really hope he doesn't end up being a love interest later, and just something more familial. Cause that's kinda.
