i couldn't stand the romance scenes at all. i skipped almost all the romance scenes after the 11 episode (in fact you don't miss much of the story if you skip the romance scenes between the 3 main characters)
There is basically almost none character improvement in any of them until the end: her ex is a childish, manipulative, obsessed and a selfish dude that thinks he owns her; the girl keep lying, making dumb decisions and is basically "um pau-mandado" (i don't know the term in english but in portuguese basically means someone that can't say no and is always trying to please everyone); the director was the nicer of them but sometimes he could be a bit manipulative too (like there is one part that he use the girl to try to find the necklace).
She and her ex-husband have a really toxic relationship so i never shipped them. In the beginning i shipped her with the director but at some point i couldn't ship her with any of them. i hated the ending (in fact i barely saw the last episode. while skipping between scenes i found with who she end up)
Still never understood why the director's mom was opposed to their relationship. i even thought that could be half brothers but i don't think it was explained (unless i accidentally skipped)
I just didn't abandoned the drama bc of the whole mystery/crime (in fact the detective saved the drama. the only good character). about the whole mystery it kinda a bit meh (could be better) but is not worse than the whole romance plot.
