Hello there @abs-oluteM found you since red-sleeve era and glad that when I watch 2521 live I don't need to find any new moots, since apparently almost all my moots (since doyoulikebrahms-era) also watch it! Yay!
Here's what I was talking about 2521 sign hanging on the wall - it's on eps 2 :
and yep @ktcjdrama the sign re-appear on eps 4 when the present NHD's mom talked about she met Yijin a month ago, this time it's more clear and not hanging on the wall. Could somebody translate what does the sign read in hangul?
and just now I rewatch the scene when present NHD's mom asked Kim Min Chae does she know Baek Yijin, and KMC's facial expressions is kinda sus.. I don't know, maybe it's just me get overthinking abt that. But with the 2521-sign in the NHD present office/gallery, sure it's the Writer/Director doing giving us clue, or maybe trick us..
well, Saturday is only 3 days away! I'm quite sure in the next episode we will get another hint about KMC father. And so far, 2521 is the only drama that takes the real-world situation of covid-19 as background story so yep, it must have some revelation about the story.
