Maybe the kr raws are different? 20 might be korean age (+1 year) so they're 19
Eh wait wait. Japanese higschool student graduate at 18 years old in march....
Maybe just maybe
Well I am lost
They just want to make the sex is legal in this translation
I've red on different forum it's +2 years because
1) they're adding a year at each calendar new year and
2) it's starting at birth > so they're "already" 1 year old at birth...
So that could add up to 20 yo...
But that was on Korean age, I don't know about Japan... ╮(⊙…⊙)╭
Oh, I think I just got it. Could be wrong, but in Korea, everyone is considered a year older on New Year (not on their birthday).
Plus they are already considered 1 year old at birth as the comment above me said.
So in Japan they could be 18 years old (+1 since they are 1 at birth, +1 again since the new year has passed, adding up to 20 yo in korean age)
Ok I got it. But wearing a high school uniform at 20 years old leave me the "weird" impression
Im so confused why are there little boxes with their names and (20) in the first couple pages for intro when 1) they shouldn’t be 20 at their high school graduation and 2) the jp raw didn’t have it at all??
