Unrivaled Countenance (2024)

Similars

the story of lovers from two different realms: demon and human. I actually liked this better than big production with big stars
Love story and marriage of demon lady and a man who loves her with all his heart. Fragments of Kylin had stunning scenery and interiors. This was a much lighter (more comedy) series.
Both FLs are powerful and skilled in magic, and end up transferring their souls into the body of a weaker, powerless girl. The original body is burned, and then end up aiding the ML as well as being under his protection.
