the author actually revealed it on twt that Milo should have been much older. they changed some of the character setp and style and the beta version also looks good. Beta ver MC have similar build with Uncle A but Nachioboy changed it and made him slightly slimmer than Uncle A. So Yeah. Milo is an adult and some of their arts on twt have milo as an adult (aside from the mem they drew abt milo, child ver, who looks so shock and in dismay)

The artist's twitter acc suggests that they have a huge thing from super buff big manly men so I don't think there's anything to worry about in that regards. (The characters in Mr A's Farm are twinks in comparison of the art the artist drew before working on this Mahnwa lol)
What I do worry about however is what it means that they used old art they happened to have laying around as as the bonus content.... Does that mean the artist is too sick to draw?? I hope that's not th case and that they're OK.
I love this manhwa but why tf they have to age up the son on this one?
