Overall, it was pretty disappointing
It had started nice but it went slowly but surely downhill
Mostly because the three main characters feels really irritating or misplaced
Maytinee is supposed to be the villain of the story but she is actually more likeable than her doormat second sister or than the manwhore male lead. You can’t help but feel pity for her because she lacked of love and was constantly pushed to her limits by her third younger sister, which drives her to become the murderer she finally becomes. We can’t help but feel that she could have ended differently, had she received the love that she needed. and for that, we feel only but pity for her. Moreover, her dark aspect make her more complex and more interesting as a character than the others. Besides, the actress’ acting is strong and makes us feel all of her charisma.
On the other hand, you have her second younger sister, Darika. The writers want us to feel sympathy for her but they fail, as she appears weak, annoyingly good and boring to death. It feels super irritating to see her being so caring with everyone, even when they persecute her. Besides, the actress’ acting doesn’t help, as she always seems to be nervous, like she’s about to be beaten. And I find it just incredible that the writers try to present her like a victim and a good person when in the end, it turns out she was actually an accomplice of murder all this time, even if it was by weakness (and it’s pretty nonsensical that she doesn’t get arrested for that in the end). Her sister may have been the real murderer but at least, it is openly admitted that she’s not a good person.
And the male lead... AKA manwhore of the year. At some point, he even kisses the eldest sister, while having a crush on the younger sis. Huh, seriously ? I don’t think I need to say more. He had started nicely as he was just trying to know more about his brother’s death but at some point, it seems to become secondary to him.
So these two characters are supposed to be the main characters but they are the most irritating while it feels like the villain should be the main character. This destroy what could be a good story.

Otherwise, the story is nice : plenty of suspense, mystery and darkness. However, I repeat, the main couple stops from fully enjoying the story
