Great other works by the actors?

Looking for recommendations for any work done by the actors in either season 1 or 2 that is notable. My favorites, like a lot of folks I’m sure are Jung-Jae and Byung-hun. I imagine Byung-Hun HAS to have a few other roles where he’s playing the heavy. But, honestly, my gf and I are looking for more compelling K dramas to watch. Squid Game is my first foray into K-Dramas, so Thanks for anything you can come up with!
