Yaya must had been ordered to be extra sweet and ultra cute in this series. She is burnig the scenes with her charm but sometimes this cause unnecessary 'big' and messy acting.
However, acting is not a problem at all, next to the amateurish writing. There are some scenes making fool of viewers. For example; Matthana dropping her shoes to the ground from the tree she climbed sneakily in ex-celebrity Tawan's garden and when they cauught her and make her out of the house she is not saying a word about her shoes. Writers so lazy that they are not capable to find a proper way to leave the shoes at the garden. They need those shoes later in that house for story reasons but they make it in a way that Matthana is an idiot not recognise she doesn't has her shoes on her feet in a rainy weather. That's just a little example. There are lots of such errors.
Also, Matthana begining to work in Tawan's house with a fake ID and when they found out this they don't report her. Now this need a proper reason. A reporter acting like a maid and begins to work in your home with a fake ID and searching for your private life... There is a serious crime here. A guy like Tawan who hates reporters does nothing for it, no report to police?? That's ridiculus.
Bad guy is so evil and extremely determined to get his revenge from Tawan, so you're expecting something Tawan did to him in the past. But you are learning at the end that it's nothing. In a shockingly stupid scene, he says his foster parents raped him, because he went with them from the temple of orphans instead of Tawan. I mean he needs someone to be angry other than his rapist foster parents and he chose Tawan for lliterally no reason. I pity to he writer's cluenesness. Other bad character Risa is very underused that why they need that character in the script is beyond me. So, writing is shamefully messy and director is not helping too.
Aside those, Maya Tawan is still fun to watch. Yaya has big screen time, especially in first episodes she is nearly in every scene which is a big plus. Romance is satisfying, supporting actors are all good, also there is not a single annoying character which is very rare in this kind of lakorns. If you can avoid the story errors ect., it has a good rewatch value.
A side note: This is a part of the Three Muskeeters series but they're not the three muskeeter reporters' story. Here the main story is Tawan's backstory and his struggles and big sorrows are all boring to me that I would liked to know more about Matthana's life instead.
