EXACTLY i was thinking they were calling him rookie because he's younger with less experience in gangs
"rookie" is really just used for people who are new to something with little to no experience. It doesn't entail young, but I get the confusion oml
I’m not sure if they do this in korean hs but maybe he had to repeat the year a few times?
think of it more like a figure of speech, mc is new to the gang, acts childish most of the time, maybe in the ml's eyes he is like a kid sometimes
god i responded to the wrong comment
I was so sure the ML is older than the MC aside from the fact he kept calling him "kid". Now what do you mean they were classmates?
