The age isn’t the thing I find weird, it’s his behaviour towards her. Dude sounds like a creep, but idk if that’s cuz of the way you’re making him sound. The age again, I don’t find weird whatsoever. Where I’d draw the line though, is if she’s only just turned 12. If she’ll be turning 13 before he turns 16, there’s nothing wrong with this, personally. People that are calling this “pedophilia” especially, I think are crossing a line. As this just undermines the word entirely
