Totally fake.
However, if it weren’t for the greentext formatting, this could be a hell of a hallmark movie.
It’s cheesy for sure, but there’s a good idea buried under that. I’d go as far as to say that, with a delicate enough hand, this could be a solid to great short story or novella. But you’d have to really go easy.
This would be depressing as shit if it were true, not really a hallmark movie. I’d be traumatized if I found out a dead brother had done something like that for me and I just blew it off.
