Royal Doctor (2023)

they are both about the Female lead traveling from the present to the past. In both series the female lead has difficulty adjusting to the past but they are both able to contribute in their own way.

The competition between modern medicine and traditional medicine is seen in both dramas. In korean drama male lead travels to modern era while Thong ek is opposite, female lead travels to ancient era.

Originally was supposed to be a sequel to Thong Ek but storyline changed still basic elements about Mor Luang is still similar to Thong EK such as leads cast, herbal, and historical time period.

In both series the female lead travels from the future to the past
in both series the mother of the male lead is against the female lead

Both are set in Thai historical periods, I'm not sure how similar they are in plot wise but the first combination of Mario and Kimmy was similar in many ways, this is not a sequel but a similar story to it, so I decided to add this, but this lakorn is not released.
