idk how similar but the trailer had a similar vibe.
- "heavenly" emperor/leader x dark-ish FL
- even the poster got a similar look --> ML's hair and crown piece

Both have a cunning and powerful demoness as the lead fl , the lead couple are i think gonna be demons, the setting is the same plus both are xianxia which makes these two not only the same becauae the characters but also becuase of genres

Both involve the FL being rescued as a child by a man and dedicating herself to some quest, becoming entangled with the ML as a result. Ultimately it's revealed the man and the ML are the same person because of time travel.

Both dramas start in the mortal realm and there is a background story where FL is a kind of divinity created to the harmony of the world in rough. Both have a great chemistry between the main leads.
ML and FL are quite powerful in both dramas.

Both couples are rivals or in the opposite sides
Both female leads are flirty to the male leads
Both female leads have ulterior motives to the male lead
Love triangle
