This is pretty popular in Thailand I think. I see it all over Twitter. I saw the storyline with cheating husband, and noped out of it.
I agree with Spanky, this isn't those typical cheating husband storyline. It's much much more. It's a lakorn displaying how even after a man has hurt her, she is able to continue moving on. Also, it shows how even after how badly he effed up she still tries to manage a good dynamic with him for their daughter's sake.
