I think what Little A did back then made the farm animals become human not because humans mutated or it can turn both humans and animals become mutated because I think that the dog who was with him became fluffy now and Uncle now having ears. And the reason why he's going to therapy and his parents becoming protective was because he might turn into one??? And and idk but it might be one of the farm people who sent the letter to Little A posing as his Uncle, because I doubt it's the Inspector or G. Seeing as G doesn't want him there and the Inspector doesn't seem to care.
Though there are some scenes that wasn't properly explained it's definitely one of the best ABO that I've read. Also I was hoping that Sangyul would be able to manifest as an omega fully due to Reok's fluids and then we'll get to see a baby but I just hope the last ch was hinting into a possible pregnancy (っ˘╭╮˘)っ
