If you can get past the fact that ML really looks old most of the time - though he is pretty good-looking and a natural actor - you will enjoy this classical lakorn that employs some old tropes, like the girl being sold for debt, unexpected pregnancy, revenge, rich man/poor woman etc, all DONE RIGHT. The FL is really good-looking, interiors/settings are luxurious, fashion is ok overall. Action is too rushed in the end, not enough romantic moments to justify the hate-to-love transition.
Some side character steal the show... like the FL's mother and mother-in-law, they are also funny and round characters.
The SML - there are two of them actually - dont count, they are either boring or annoyingly ridiculous.
SIDE NOTE: the FL starred in a very similar lakorn, Raeng Ngao (2012), with same love triangle : uncle - nephew, but in this one she looks better, without the weird contact lens (?).
Right now i wouldnt rewatch this, maybe in the future?
