Tale of the Nine-Tailed 1938
구미호뎐 1938Checked and re-read
The original romance no longer drives it, and the show is better for that. This one hands the screen to Lee Yeon and his brother, with a new bench of antagonists around them, and what comes out is a comic buddy adventure in 1930s Gyeongseong with sharper villains and a tighter plot than the original managed. It is also much lighter: season one could hurt you, and this one is having a good time. You can start here, because the two stories barely touch, which makes it the right entry point if the season one romance was the part you disliked. Just know the last ten minutes are a trailer for a season that never came.
The Nine-tailed fox makes a crash landing in the year 1938, an era of chaos, and he struggles to return to the present.
Slow start Episode 5. The first four hours are a period tour of Gyeongseong; episode 5 is where the trio at the centre starts working and the villain gets a plan worth watching.
