I had a crazy theory before S2 dropped. I always thought that the Seo In we see here was not actually him but his brother. I had a theory that Seo In's heart was transplanted to Jaewon and now Jaewon stole his identity but idk anymore, it's the moles that's throwing me off and also no surgery scars but still nothing that money can't fix and he has plenty. But still, could be a possibility cuz both of them are crazy.
Dan's grandma said he became a heavy drinker few years back so how many years has it been since Dan left Seoul? I can't remember but I thought it was just at least half a year ago? Or maybe I just didn't remember it correctly and he's always been a heavy drinker even before meeting Jaekyung.
if you mean when dan moved out of jaek's house its been like 1 or 2 ish months? also iirc dan's always been a heavy drinker since it was mentioned once that he had a good tolerance for alcohol
He was probably drinking also during the time he worked in that hospital, before he started with JK, where that old fart harrased him
