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)
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??
