Both FL are hard working, smart and deep down very nice, but they come accross as ambitious and disingenuous. They're willing to be the bad guy if it can help their ex move on. In both drama, they are in a love triangle between a hardworking guy and his younger "brother" who is a heir, which makes the guy's relationship harder. In both shows the FL is humble and determined, willing to take crap from her superiors, but she also knows when to stand up for herself.

Both lakorns, the female protagonists are both getting out of a bad marriage (except Mia 2018 has no marital violence) and meet a great guy who helps them gain confidence in themselves.

Very similar plot, except Mia Noi's FL is not an orphan and the ML is not a rich guy and he doesn't ever judge her. Maybe Nang Sao Som Lon will be a bit less gritty and fluffier/funnier than Mia Noi

From the synopsis the two dramas seem similar: the FL loses her boyfriend to a rich girl. Then she meets the rich girl's brother/cousin and he falls in love with her and court her. Lub Luang Jai is okay but there is not much passion between the leads.

The dutiful wife is cheated on by her husband whith someone really close. She has to learn to stand on her own two feet and gain her independance. The main leads are different though. In Mia 2018 the FL is a frumpy mom who lost herself in her role of wife and mom and has to find herself. In Roy Leh Marnya, she is independant sexy and young.

I found myself wondering if The Devil Punisher was not a remake of Goblin. They have somewhat of a similar esthetic (though Goblin is much better made); look at how similar the show posters are!
If you like stories about ghost fighters and amnesia, then you'll love Goblin.
