Highly anticipated Netflix K-Dramas for the rest of this year

A 22-episode series, even longer than "When Life Gives You Tangerines." The production budget is massive. It seems to be the next big thing after Squid Game Season 2-3 (in the 100 billion KRW range), whereas "When Life Gives You Tangerines" is in the 60 billion KRW range.
The writer is very famous, and the director is the one who directed "Coffee Prince."
Netflix has made a huge bet, trusting the writer.
