Casa Dourada Amor Oculto (2024)

Both FLs are from modern day and meet the MLs who are in/from ancient times. Both MLs are supernatural beings whose life is tied to a tree, with the tree reflecting what happens to them/how they're feeling (blooming withering, etc.).

In both, ML is seemingly an immortal. Romance between immortal and mortal. FL is also seemingly a reincarnation in both.
