ok, i'm estimating that at introduction, the kid was ~9-11 years old. the tower master, i believe would probably been ~18-21. at this point, our characters have aged, but they are still clearly not adults– let's say ~16-17. this would put the tower master at 24-27 years old, which is already a red flag.
But then again, you have to consider that this author doesn't really age people: consider our main two, who have looked the same since the story ended to now, almost 2 decades later. This means tower master could be a lot older.

Im guessing the kid 11/12 n since the author said he youngest to be approve the head master 17/18.. USA we considered the age of an adult 21 once u hit 21 nobody has a say on who you date with .. people still have opinions ofc but it is what it is, .... especially when a person doesn't pay your bills ... we pay those people opinions NO MIND.... Now here the origin is Asian so we all now the adult age IS 17 but I DON'T THINK the author gonna have him touch the "kid" until he ready unless the "kid" might do it by himself idc as long there is consent. Yes it would be nice till he wait for him to get older but it is what it is......
1) the tower master can square tf up, i'll beat the shit out of him for even trying to discourage my bby
2) if this turns into a romance between the boy and the tower master, WHO WE KNOW IS SIGNIFICANTLY OLDER THAN HIM, i am going to lose it.
