The storyline about revenge is almost the same. The young princess (FL) also want to get revenge for her family and the ML loves and helps her.

Same author, although the story line of Love of Thousand Years deviated more with somewhat questionable execution for LoTY. Fantasy elements. Involves lifetimes and the male lead sacrificing for the female lead. Great acting from the male leads of both shows.

Similar concepts of lovers being fated for each other but love of thousand years happens over many life times dance of the phoenix is more of a time travel/childhood lovers situation, has similar tropes with the fantasy and politics, both also started off great but ended up being okay at best

Both are kind of similar because at first ML is chasing FL in both dramas and they have similar kind of feeling as how the story progresses.

Gutsy fl with a painful past and a flirty ml who loves nothing more than to just keep looking at her adoringly. Political intrigues, secrets, fights and some dashes of romance.

In both drama one of the mcs seeks revenge while the other accompanies them throughout their journey. Bickering, adoring gazes, secrets, sacrifice and lots of flirting from one of the mcs.

Charming male leads, spunky female leads with big attitudes, and a whole ton of eye candies... all combined to create some really good chemistry~

Both go through reincarnation and have the ML watching the FL. Both MLs have magic and are immortals that fall in love with a mortal. Both FLs change people as they are reborn and the MLs always help the FLs.

In both of the stories the ML waited for FL's reincarnation to love and protect them for a lifetime.
