Güneş is a 35-year-old literature teacher from Izmir with 3 children. They live their own, happy lives with their 17-year-old fraternal twin daughters Nazlı and Selin, and Peri, who is two years younger than them. The marriage proposal of Haluk Mertoğlu, a famous businessman from Istanbul, astonishes Güneş. Güneş and Haluk's relationship comes to light when Nazlı becomes suspicious of her mother and proposes marriage. Nazlı is completely against this marriage and will do her best to prevent it from happening. While Selin thinks that this marriage is a great opportunity for both her mother and herself, Peri, the youngest, says that the choice that makes her mother happy will make her happy too. Despite all the problems caused by Nazlı, Haluk has no intention of giving up on Güneş. Haluk Mertoğlu wants to host Güneş and her daughters in their home in Istanbul to introduce the families. Güneş and Haluk's sudden marriage decision also provokes reaction from the Mertoğlu family.

Nazlı, who overheard Haluk's phone conversation, becomes suspicious of Haluk and decides to follow him. Although Savaş is unaware of anything, he finds himself involved in the events with Nazlı's pressure. Mert, who blames Savas for Melisa's disappearance, decides to hurt Savas. Nazlı was also dragged into Mert's trap along with Savaş. Ali warns Selin to stay away from his friends. Selin doesn't care about Ali. Tuğçe, who sees Selin side by side with Emre despite what happened at the birthday party, truly regards Selin as her enemy. However, Selin will not leave what was done to her unanswered. Selin, who first puts Tuğçe in her place, hits Ali at his most sensitive point. Rana and Sevilay join forces against Güneş. Sevilay's claims about Haluk confuse Güneş. For Güneş, getting used to Istanbul will be harder than she thought. Meanwhile, Nazlı's pursuit of Haluk draws Güneş to Haluk's boat.
