Goblin: The Lonely and Great Godstars Lee Dong-wook and Yoo In-na reunited in 2019 for another romantic K-drama, and their second collaboration was just as good. Released in 2016, Goblin immediately garnered popularity. The show, which was led by Squid Game's Gong Yoo and The King Eternal Monarch’s Kim Go-eun, is often listed as one of the K-dramas everyone should watch. The fantastic yet sad love story was incredibly engaging, and so were the performances.
