it's just a little strange how the way little A sees uncle is a buff bearded man who's so happy-go-lucky, but when K explains him, uncle looks fragile though he has muscles and no beard at all. and he seems different from the guy at the bus? Idk? maybe he's uncle, maybe he's not.

I don't think he's misremembering and instead it's probably just a different perspective; since little A was a kid, the uncle probably looked/felt bigger to him and also adults often behave differently towards children than towards adults so it's entirely possible for the uncle to have put an "strong reliable uncle" act in front of little A when he was a kid. It's also possible that the stress of this entire messy situation with the hybrids made him more anxious/less confident.
Since the last time little A saw his uncle was years before any of the "farm animals" saw Mr A for the first time it's also entirely possible for little A to only know him with a beard and the hybrids to only know him without.

seriously though, I think it wasn't Mr. A who sent Little A the letter. could be someone else, 'cause why would Mr. A be so shocked to know that there's a young man headed to the farm (if that was Mr. A on the bus)? and I think the reason why Little A's parents constantly sends him to therapy is because he saw the reports about the mutations (this is just a theory), and he's Mr. A's son.
also, I NEED NEW CHAPTER NOOOOOWWWW I'M GOING INSANEEE!!

wait, if that's uncle A, why was he so shocked to know that some kid went to the farm?
and if that IS uncle A and he doesn't know that little A went to the farm, then who sent little A the letter?
and also, about the box, maybe little A found out about the secret about the mutations, that's why his parents sent him to therapy, no?
I just hope they update 2 chapters every 10 days, I can't wait for more
