I NEED someone ro tell me how old he is cuz wth

if your talking about the market boy hes 23, as stated when the younger brother was reading his file. ( sorry bad at remembering names )

Hey, dunno if this counts as a spoiler byt I read ahead and Chungrim is 25 (or that's what I got from the fleeting mention of him being two years older than Sung-kyung).

all that for them to be 2 years apart
