Nueng Dao Fah Diew (2018)

In both these dramas, Male Lead is disguised as eunuchs to enter the palace.

The protagonists pretend to be a eunuch to enter the palace and investigate the truth behind...........

The same couple act in both of these dramas.
If you liked the historical aspect of either of these dramas, what the other one!

Ka Badin is similar to Nueng Dao Fah Diew because both are historical lakorns where the main male lead is fighting for Thailand.

The two female leads are happy-go-lucky, although one was very young with the garland still on her head and the other was/is only reaching womanhood at the start. While some of the story plots diverges from each other a lot is still the same, it also seems to be around the same time period.
Both are period dramas based on an impeding war that could ruin their country’s current dynasty, while also filled with romance and the MLs spartly struggling with their budding romance over their duty.

Both are historical dramas with fun female leads to watch and really attractive main leads who IMO both have great chemistry to keep you invested. Also both have annoying side characters but nothing to drastic to keep you from watching

The story revolve old story of thai and both show have the main FL character very strong even during ancient times which is rare.
