kang min is 20… hes a highschooler but hes 20yo cuz as you can see, hes a little slow and stupid baduka
Koreans count age a little differently though, starting from conception. So usually a 20yo in Korea would be considered a 19yo elsewhere - not a huge difference, but just some extra context lol
Expecting gentlemanly behavior toward a high school student is weird and the age gap makes it even more concerning
