Boths dramas are comedies set in Joseon and both have some serious aspects. FMs are poor and hard working. They both hide their soft sides but also care for their families (brothers). MLs also have some similarieties. They are upright and serious flowerboys.

Both are fantasy-historical drama with mitical creatures. And both are love stories where important role plays destiny and cureses.

Both fantasy dramas are set in fictional historical period and tell a story about magic, curses and fate. Both deal with a royal famillies and shamanism. And both are love stories with young actors.

In both dramas, one of the main characters tries to gain the trust of the other in order to obtain secret information using a false identity.

ML leads are simillar. They are handsome and know how to flirt. They are cold and manipulative and intentionally saduce women without deeper emotions.
Vibes of the dramas are simillar. They are dark yet realistic. I have impression that the acting and camera shots are also simillar, with many close ups of the faces.
