Fun fact: Sang Woo's mother as well as a probably-teenage Kang Cheol appear as cameos

Imagine Beating someone up then the guy you beated up is your boss

@itzsillybob810

I mean, yeah. It is literally referenced in the show in some dialogue, for all three of those.

@margarethmichelina5146

Also, the returning characters for 3 years are having their downfalls: 
Jung-Bae / Player 390 lost his business which was a restaurant if I remember and then got divorced and his kids are being taken by his ex-wife, just like Gi-Hun
The loan shark looks like lost his previous job as Gi-Hun paid him to find the recruiter and he looks completely serious unlike in season one when he was sadistic
The broker still has his job but he looks jaded and lazy even when people like Gi-Hun and No-Eul (Guard 011) gave him money, he refused to do it and complain a lot.

@Cyber_PlaysYT

NOOOO WAYYYY I THOUGHT 390 WAS ME:0:0:0 
Fun fact: gi hun is in both seasons also!!!
