Talay Luang (2021)

Story wise both lakhorns have lots in common.

Both ML´s are rich and FL´s are islanders.

In both lakhorns ML gets amnesia and meets FL on the island to later on get amnesia again and forget everything about FL.

Haven't watched Talay Luang yet, but based on synopsis alone:

Both dramas have an amnesiac rich male lead who falls for a simple country girl, and then is forced to leave her and return to his fiance/girlfriend etc when his memories return, but he loves the country girl and after much angst ends up with her.

The only difference I can think of is that Talay Luang is centered in a seaside town and the FL in STLDFM was from the rural countryside and owned a farmhouse and b&b.

In both dramas the male leads loose their memories, personalities change, and are taken in by the FLs.
