It describes the traumas experienced by the anxious-avoidant son of a codependent mother and an emotionally unavailable father.
The mother got married and had a kid in order not to be alone. Even though he is extremely unhappy, she cannot leave the marriage. She is too fond of his son. All of these facts make her codependent.
The mother cannot express her feelings to her husband because her husband is emotionally unavailable. That is probably why she created an identical partner in her mind with whom she can talk about her feelings easily making her feel relieved. The father's reaction to his son's song and bad skills in Math classes, etc. Also proves his emotional unavailability.
The boy develops an avoidant attachment style due to his parents' quarrels and the lack of a father-son relationship, and an anxious attachment style due to his mother's overly attached attitude towards him. His judgmental and patronizing attitude that led to his first breakup shows his avoidance side, his post-breakup regret and the fact that he fell apart in 8 hours after the breakup shows his anxious side. He exhibits a similar attitude in the encounter with his ex years later. Ultimately, he matures at a very early age as someone who can't belong anywhere.
I find it one of the greatest work in Turkish TV history. Although it is a dramatic story itself, they balanced it by adding absurd comedy elements. I laughed out loud from time to time, some scenes had cartoon-like characteristics.
