Faruk Gencer, the boss of Gencer Seramik, did his best to cure his sick wife Efsun, but lost her in Bodrum on their way back from treatment. As Faruk returned to his mansion in Istanbul with his children after losing his only love Efsun, he was unaware that they would be the victims of Serap's envy. In fact, Serap had come to that house with them reluctantly at first. She did not want to babysit the children of Faruk Gencer, whom she worked as an assistant, but she could not say "no" to Piraye Beyzade, a prominent member of the Muğla gentry. Because Serap's mother Mürvet was a foster child of Piraye Beyzade and Serap had started to live in the environment she had always wanted as Faruk Gencer's right-hand woman at Gencer Seramik. Serap's main goal was to settle down with a noble and wealthy man from that circle. But now Ms. Piraye wanted to entrust her grandchildren Nisan, Naz, and Ömer to an educated, reliable, and loving woman, and Serap was the perfect woman for the job.

"Why?" Serap asked when she settled in Faruk's mansion. "Why can't I have it all?" After all, since she was born in the outbuilding and not in the mansion of the Beyzades, life had done her a great disservice with the twenty-meter distance between the two houses, and Serap, who had to look "good" to close that distance, had tried very hard. But Faruk Gencer, whom she now knew very well, was a unique opportunity for her to close this gap! Yes, it was not Serap's dream to marry a man with three children, but that was a later matter. Now Serap had to enter not only the home but also the heart of this man who was very devoted to his deceased wife and children; she had to become Serap Gencer. But there were obstacles that Serap did not take into account. Faruk's eldest daughter Nisan, Cem, the architect of the heartbeats she couldn't stop, and Efsun's close friend İpek!
