Queen Love

They both have similar stories that have connections to the past and future with issues and deaths that need to to be resolved. The time travel is done with the original body in both dramas. They both have symbolism and connections to butterflies and the same feel to it. The same people that were in the past are also encountered with the same faces on both dramas in the future. There is also the theme of longing for someone so much that it trascends time and space. Both take place in Joseon and New Joseon and Both are also based on webtoons.

This has the Vampire storyline that everyone needed to be satisfied with what hapened to Gwi.

This drama has the execution that SWWTN lacked.
