In both dramas, the FL is a warrior and extremely good in their combat/martial arts skills [PS: In A Journey to Love, technically, she is a spy but a badass one who is much stronger than any army general.] . Both the ML are a leader or heads of an army/hall (basically a man with responsibility).
The male lead in both are caring and there is a real romance in both dramas.

Common points:
- Strong Female lead and solid male lead.
- Both FL recognized the strength of the ML from early on.
- Both ML recognized the strength and singularity of the FL.
- Both have quite some amount of action and romance.


If you liked one, I think you will probably like the other one!

Similar:
- Lead get pregnant
- FM gives birth without the ML knowing, raising the kid a few years on her own
- ML successful (as always in dramaland)
- Cohabitation

Different:
- in LNF the ML and FL did not know each other really

Basically a remake but in Thai !

All the characters are interesting ! love the triangle in PH Thai

Both contain a similar plot : one girl who became princess within a couple of weeks !

In My princess she is the real princess in Princess Hour ( Thai) she "have" to marry the prince !

Both are funny and some good romance :D
