Believing that she will lose her eternal happiness if she cannot meet with her first love, Ada falls in love with Rüzgar, who confronts her at university and needs Turkish citizenship in order not to go back to his country, and proposes to her. The only purpose of this marriage for Rüzgar is to get citizenship, and for Ada, marrying her first love is to beat her luck. On this happiest day for Rüzgar to receive citizenship, Ada got into an argument with the founder and editor-in-chief of the popular social content platform Bizdeböyle.net, who came to the cafe where she worked. This argument resulted in her being fired. When Ada goes to the company where she works to see Rüzgar, her whole world falls apart when she sees him and her colleague Tuğçe... In order for Ada to win Rüzgar back, she has to get a job at Bora's company and for this, she has to make herself accepted by Bora, a man she hates who is very difficult to please unless you know him better. Will Ada be able to do this?

Before Ada delivers the entire video to Bora, she makes a deal to ensure she stays at the company, but being Bora's assistant is much more difficult than Ada thought. Ada, who has become the number one gossip topic at the company, gets the nickname "27" because she is Bora's 27th assistant. While the employees bet on how permanent it will be, Ada tries to stay on good terms with Bora. As she starts researching to get to know her rival Tuğçe better, Rüzgar, who keeps his marriage a secret, sees Ada as a threat to the company and tries to drive her away. After the video scandal, Bora gets an opportunity to tidy things up. Learning that the other party will come to the extremely critical business dinner with his wife, Bora decides to go to the dinner with Tuğçe. On the other hand, Ada sets up a game for Tuğçe so that Bora can go to dinner with her and she succeeds. The meal, which started out perfectly, turns into a nightmare when Tuğçe and Rüzgar come to the restaurant.

Tuğçe asks Ada to inform her of Bora's daily plans, to act as a kind of spy. Realizing that Tuğçe likes Bora, Ada accepts this offer. Thus, Bora and Tuğçe will be together, and Rüzgar will return to her. Ada takes things one step further and starts mentoring Tuğçe about Bora. She enters the chat program that Bora uses for writing articles and tells her to chat with Bora without giving her name. Realizing that Tuğçe is not very good at correspondence, Ada writes to Bora herself. Impressed by the conversation of the mysterious woman in front of her, Bora thinks that he has found good material for his new series of articles and invites the correspondent to dinner, and Tuğçe gets very excited. Thanks to Ada's correspondence, Tuğçe begins to believe that Bora is in love with her and offers to go to the mountain house on the pretext of a photo shoot to stay alone with Bora. Bora also invites Ada to her chalet. And when Rüzgar follows them in order to be close to Tuğçe, things will get messy.

Ada is very disappointed when Rüzgar proposes to Tuğçe, and she decides to focus on her career and win the favor of Bora. On the other hand, Ali expresses his doubts that Bora is interested in Ada. Bora, who firmly rejects Ali's suspicions, acts contrary to Ada in order to distance himself from her and asks her to stay away from his personal affairs. Ada cannot understand this strict attitude of Bora and hangs on to her work with all her might. Worried that Bora will fire her, she asks Tuğçe for help. Bora, on the other hand, makes a surprise meeting with his ex-girlfriend Fulya. Ada and Tuğçe follow Bora to the meeting place. An unexpected tension arises between Ada and Fulya at the restaurant. As Bora tries to escape, he constantly finds Ada in front of him, while Elif's fondness for Ada will cause Ada to go to Bora's house more often.

While Bora is looking for topics for new content, Ada comes up with the idea of a 'white marriage'. Bora likes Ada's idea very much and asks both Tuğçe and Ada to prepare a series of articles. Tuğçe warns Ada not to write the text, but Ada challenges her. Meanwhile, Tuğçe goes to the immigration office to research for the articles. There, she meets a person who knows Ada and Rüzgar closely. Ada and Rüzgar are forced to cooperate in the face of the danger of their secret being exposed. Ada works tirelessly to make good use of this opportunity to showcase her writing skills. When Tuğçe realizes that Ada will not give up writing, she puts her plans into action. Thus, the rivalry between Ada and Tuğçe transcends into hostility. On the day they will deliver the texts to Bora, Ada confronts Tuğçe's dark side.

Bora, seeing Rüzgar in Ada's House, leaves without waiting for an explanation. Ada goes after Bora and tries to explain the situation, but clearing Bora's suspicions will not be easy for Ada. Trying to find out the source of the 'white marriage' article, Celal wants to visit the company and meet with Tuğçe. Celal meets Bora when he cannot find Tuğçe. What Celal, who has increased his visits to the company, does not know is that Ada and Rüzgar work there. The Bizdeboyle.net team decides to go to a relationship camp to research for a new article. Bora, Ada, Tuğçe, and Rüzgar join the relationship camp for two days to observe. Little jealousy arises between Bora and Ada, who go to the camp as a couple. Feeling remorseful for not being honest with Bora, Ada decides to tell the truth. Will Ada gather her courage and confess her past with Rüzgar to Bora?

Celal's arrival at the company makes things quite complicated for Ada. Ada is tired of trying not to reveal the facts and is on the verge of a difficult decision. Feeling guilty for the lies she's told Bora, Ada decides to quit her job. Bora is shaken by Ada's sudden decision and begins to question the reason behind her giving up her dreams in a snap. As Ada begins her search for work, Bora, who has lost trust in Ada, orders her to be cut off from the company. Is Ada, who is faced with a difficult test between her dreams and her reality, going to tell Bora the real reason for quitting? On the other hand, Celal visits Ada's house to observe the marriage of Ada and Rüzgar. Ada and Rüzgar have to do what Celal wants to handle the situation.

Ada explains the lie she told Bora. Unable to accept such a lie, Bora says he doesn't want to see Ada again. Ada, with the weight of the words she heard from Bora, wants to re-enter the company and prove herself to Bora, so she talks to Rüzgar to help her with returning to the company. Since Rüzgar has no other choice but to help Ada, he takes his chance with Tuğçe. With what excuse will Rüzgar ask Tuğçe to get Ada back to work. Ada returns to the company with a mission that surprises everyone. Disturbed by the disregard for his authority, Bora intends to force Ada out. He gives an impossible task to her and Tuğçe.

While Ada is trying to fulfill the given task, she also is caught up with looking for the ring with her name and Rüzgar's. Ada and Tuğçe put their plans to interview Kuzey Batı into action. Bora cannot hide his discomfort about Kuzey's proximity to Ada.

Not wanting to lose her place, Ada joins forces with Tuğçe to eliminate the assistant candidates, but a surprise candidate who suddenly appears disrupts all their plans. Bora's childhood friend, Meltem, begins work as an assistant. As Meltem and Bora's sincerity infuriates Ada, Ada, realizing Meltem's suspicious behavior, opens the situation to Tuğçe and asks for help. Ada and Tuğçe follow Meltem to try to spot one of her shortcomings. Ada warns Bora about Meltem, but Bora thinks Ada is jealous. But Ada rolls up her sleeves and reveals Meltem's true face to Bora.

Bora takes action to clear Ada's doubts about Meltem. Ada finds evidence that will reveal Meltem's deception and shares the evidence with Bora. While she thinks she has finally succeeded in convincing Bora, she is unaware that things will get even more complicated.

Finally, the true feelings of Ada and Bora are revealed as Bora declares his love for Ada. The lovers decide to hide their relationship, but it won't be as easy as they think.

Bora is not satisfied with the reason Ada gave for their separation and tries to learn the truth of the matter. Because Ada cannot tell the truth, she claims the bad luck of the women in her family.
