Si Nae Ha Saree (2022)

Same ML actor, director and writer and also a fantasy seeting.
Both FL are fashion designers.
Both working with a ghost theme, even in "Look Mai Laai Sonthaya" it isn't a real ghost.
In "Look Mai Laai Sonthaya" the ML have superpowers.
Give it a try.

It has the small hints of horror plus romance that you can enjoy. Both shows talk about royalty and how they are betrayed by love. I feel people would like this type of drama. (I hope!)
