I feel like her anger is justified tbh cause she know Thawat would not believe her if she went full head and announced it, the plan is quite brilliant tbh. And notice how she did not trashed the small house immediate even after Wuttha showed her the cctv. And the next morning she was still holding it in. And yet still Nai lied by telling her he met a client last night.
I believe someone mentioned how Nok's weak point would be her dad, Thawat. He must have been a very busy dad who barely made time for his daughter so he tend to give into to her a lot, to make up for it. And to have Khae in the picture taking all of her dad's attention, and who is in it for her dad's money - even for me i wouldn't want such woman near my dad. Call me childish but I'll fight for it cause it's my dad's happiness!
Thawat handled it very poorly tbh. He should really listen to Nok instead of blindly asking her to apologize to Khae's mum. Thawat is blind af rn i am so pissed at him
Oh well, to each their own i guess
