Idk what exactlyy is going on, but I’m guessing they went on some trip for infinity challenge and they were asking what subway line/number they took to get there. (kind of like bus numbers)
(you go from bottom to top in the picture, top to bottom for translation)
haha: hyung is line 4 and I’m line 3 so I win!!!
JJH: 4~ is bigger than 3~ you stupid!
haha: line 1 is the best! like number 1! first place!! don’t you know??? 1234! I’m 3, hyung you’re 4! I win!!
JJH: is ramen 3 servings bigger or 4 servings? ~~ when you’re hungry do you want to eat 3 pieces of bread or 4~~ I win!!!
haha: you’re so ridiculousss!! Is Nemo a first-rate wife or 4th rate wife??? huh?? huh?! tell me!! seeee~ because I’m line 3 and hyung you’re line 4, and I arrive in Seoul earlier, I win
JJH: this is so frustratinggg! (they say “you’re so ridiculous” and “this is so frustrating” in this cute way… so I just expressed it with more consonants lol) nemo is a specially-rated wife! it’s bigger than first place!!! uhhh… mm… it’s not that I can’t think of something to… say…. wait!!!!
haha: I’ll give you one second!
JJH: are we allowed to talk about family?? or no?? 1 second is too long for me…. I just need 0………………………00000000000000000000001 second to think!
haha: ok I’ll apologize for that! but because you didn’t say anything at first so it doesn’t matter. “twe twe twe” (basically sounds of him “spitting out” what he said earlier about nemo) I know that nemo is a super-ultra special wife! okay from no on! no talking badly about family!! “twe twe twe”
(for the next one… just know that when you say 4 in korean, it’s “sa” and “sa-rang-hae” means to love)
JJH: does…… a car run with…. 3 wheels?? or no?? you need…. 4………… this is a bit…. sad… right? do you “sa-rang-hae” your parents or “sam-rang-hae” (this doesn’t exist)?.. this is… too much huh? well.. you know…
haha: let’s make up! realizing that we’re riding on this together makes me a little emotional… i love you hyung… thank you hyung… don’t grow old hyung. heuk. *cry cry cry*
JJH: you tell a recently wedded to not grow old… wow… you’re pretty wrinkly lately too! well i’m going to rest… after thinking about tomorrow~^^..
it’s a pretty rough translation. but i hope some of the meaning comes across! they’re wayyy cute! :D.
