This is an OK series, it only started getting better when Mavi entered and Nare left, Sancar and Nare's relationship is toxic, and its not good for either of them, there is no forgetting what happened in Nare's past, she did the right thing leaving Melek because its becoming too unhealthy for her.
Whereas Sancar and Mavi's relationship is so mature, even Mavi is good for sancar with the kind of trauma he experienced in his life because of Nare. they need each other to move on in their lives which is demonstrated beautifully in episodes 37-52, Tuba and Engin are such a compatible couple no matter what series they are in, they give birth to such an amazing chemistry and bonding and maintains it throughout the series, I saw this both in KPA and sefirin kizi.
I wish the storyline was little different from the beginning and Mavi was there for more episodes.
I give it 4 only because of Mavi otherwise its a 2.
