Nihal is jealous of her father's relationship with Bihter. The whole family makes a trip to Aunt Arsen's farm. Hilmi tries to take back his money from Firdevs.

Behlül and Bihter can no longer hold back their attraction and start to kiss which Deniz almost witnesses.

Because of a secret tip to the police from Hilmi, Firdevs is caught gambling and thus taken to the police station for further investigation.

Thanks to Deniz, Firdevs is taken home from the hospital. Only Katya and Deniz know of the suicide attempt. Eventually, Adnan finds out the truth as well. In the meantime, it gets more and more difficult for both Behlül and Bihter to hide their true feelings.

Nihal sadly witnesses Adnan and Bihter's quarrels. Adnan cannot understand what Bihter was doing in Deniz' room. He is forced to tell Bihter that her mother tried to kill herself and that Deniz is the one who rescued Firdevs. In an attempt to leave everything behind Bihter suggests running away with Behlül.

Bihter tells Adnan that she wants a divorce and tells Behlül that she will leave Adnan with or without him.

Bihter feels cornered when Behlül changes his mind at the last minute not to go away with her. She immediately calls her mother so that she can get the letter Bihter wrote for her husband before he can read it. Adnan wants Behlül to be an important part of his firm and sends him to Azerbaijan with Nihat for business matters.

The rumor that Behlül might have had a fatal accident in Azerbaijan brings the Ziyagil family in dismay. Much to everyone's delight Behlül is still alive. After hearing parts of a phone conversation, Nihat suspects that Behlül has an affair and therefore wanted to get back to Istanbul as quickly as possible. His wife Peyker realizes that the woman could be her sister.

Besir witnesses a long-haired woman, whom he mistakes for Nihal, and Behlül kissing on the balcony. Only Deniz realizes that Behlül and Bihter were kissing each other in the middle of the night. Besir openly confronts Behlül with what he saw. Peyker, on the other hand, confronts Bihter with her suspicion. However, she believes that the attraction is one-sided, namely that Behlül alone is interested in her sister.

Behlül accompanies Nihal to her high-school graduation ball, where she graduated with honors as second best. The drunk Bihter calls Behlül to tell him that she loves him. An astonished yet happy Behlül returns her feelings.

Nihal faints in the middle of her examination and is unable to finish it. Behlül ends his engagement with Elif. After an unsuccessful attempt to meet in a hotel, Behlül and Bihter sleep with each other in the garden house. As it turns out, they weren't unobserved.

Bihter realizes that it must be Besir who saw her with Behlül. Especially when Besir tries to talk to Adnan in private, her suspicion becomes true. In the meantime, Behlül's former fiancé, Elif, has spread the rumor that Behlül and Nihal are only distant cousins and thus secret lovers. While the entire family is angry, Nihal seems to like the idea.

Adnan, as well as Behlül, are worried about Bither's accident. Bither is only mildly injured in the car crash. She was on her way to tell Adnan everything about her and Behlül. Even after the accident, she is convinced to tell Adnan everything. However, Behlül is able to stop her.

To anger Behlül and his inability to stand by her side Bihter returns to her husband. Firdevs - who vigorously tries to even and emend Bihter and Adnan's marriage - even plans a grand wedding anniversary celebration for her daughter. In the meantime Hilmi finds out that Bither was drunk when the car accident happened. An information he is more than ready to use to his advantage.

Bither goes to see Behlül in his house outside of Istanbul and finds him in bed with another woman. Firdevs fears that there is more going on between her daughter Bihter and Behlül. Therefore, she starts influencing Nihal with the notion that Behlül is in love with her.

Firdevs goes one step further and tells Adnan that Behlül has confessed his love for Nihal. Coincidentally Cemile overhears this and immediately spreads the news. Bihter realizes what a dangerous play her mother is willing to play in order not to lose her comfortable life.

Nihal who has hidden her feeling for Behlül over years kisses him with encouraging that Firdevs gave her with speeches. Adnan witnesses Behlül's confession about his love for Bihter.

Besir can no longer remain silent and is determined to tell Adnan the truth about the affair his nephew and his wife are having. This time Besir films Behlül and Bihter and sends the CD to Adnan's office.

Besir starts having second thoughts. He cannot see Nihal being hurt, therefore, he goes to Adnan's office and is able to remove the CD with the evidence before Adnan returns from a business trip. However, Besir, hopelessly in love with Nihal, decides to leave the Ziyagil family.

Most discussed topic in the Ziyagil household is the rumor of Behlül and Nihal's feelings for each other.

Adnan wants to hear from Behlül directly whether he is in love with Nihal. Pushed into a corner, especially by Firdevs, Behlül can only confess love for Nihal.

The Ziyagil's plan to spend New Year's Eve in New York while Behlül stays in Istanbul. When he hears that Besir has been hospitalized, he leaves to return him home to Istanbul.

Besir confronts Behlül that he knows about his and Bihter's affair.

Behlül asks Nihal to marry him and is accepted. At Çetin's party, Behlül hits Hilmi who confronted him with his knowledge about the affair between Behlül and his uncle's wife.

Adnan hears what Hilmi had really confronted Behlül with at Çetin Özder's party.

Bihter an Peyker are still hardly talking to each. Nonetheless, Peyker still visits her sister to let her know that Adnan has been informed about Hilmi's alleged rumor that Bihter and Behlül have an affair. In the meantime, Adnan suspects a spy in his environment who keeps Hilmi up-to-date about the Ziyagil household.

Bihter was unable to have an abortion. When Firdevs finds out that her daughter is pregnant, she decides to tell Adnan about it. In the meantime, Bihter hears of the news that Behlül and Nihal have decided to prepone their wedding.

While Nihal's world comes crashing down on her wedding day, step by step Adnan and the rest learn of Behlül and Bihter's affair.
