Rakshasa Street (2017)

Simliar because:

- Modern world with superpowers
- ML gains more powers and maturity during the progessing of the drama
- Wuxia elements despite being modern world characters
- Two different worlds
- Comedy elements

Both are fantasies though Moorim School is also a "school" story
The "vibe"s of the shows are pretty similar to each other
Pretty boys in both

same supernatural theme with a traditional background for 90% of the story
goofy main lead with amazing family powers
featuring the annoying ass female lead

It's basically the prequel.
It helps you understand the characters better and the storyline.
I need to get 100 characters so ignore this sentence.

Fantasy/ supernatural/ spirits/ friendship/ adventure. Martial arts & magic. Both dramas are worth watching and give similar vibes.
