all i know about this height difference thing is that i get fucked up every time i'm reading a fic and someone leans down for a kiss. like in my brain they're all the same height except yugyeom??? i am confusion
as a mostly jjp fic reader I don’t get that with jjp cus most fic writers write them as same height (or JB being just slightly but insignificantly taller). And with yugbam, Yugyeom is always taller than Bam.
but yeah writers should take that into consideration. One time I read a fic where Jaebum’s hands were described as bigger and longer than Jinyoung’s and I’m like, HAVE YOU SEEN JB’S HANDS???
