The life of determined and successful university student Firuze suddenly changes when she meets a mysterious man on the ferry. While Firuze finds herself the hero of a full-blown love story, her family's past reappears years later. While the pure and passionate love she lived was her only shelter from the truth that upset her, Firuze is unaware of the big secret of the man she fell in love with. When this secret comes to light, no one's life will be the same as before, Firuze's test will actually begin after that.

Unaware that Kağan is married, Firuze surrenders to love more and more every day. For Kağan, who feels like a prisoner in his life, time is getting shorter. While Feryat's relationship, trying to protect his family, enters an irreversible path, the nightmares of the past do not leave him. Meanwhile, Mehmet, who is in love with Firuze, finds himself on the verge of a serious decision. Çiğdem's life starts to get harder, but Ömer does not leave her alone. Leyla, who begins to suspect Kagan's actions, begins to prepare to start a great war.

Firuze, who faces the truth as a result of Leyla's game, experiences the biggest disappointment of her life. Unaware that his secret has been revealed, Kağan prepares a surprise for Firuze. The only motivation of Firuze, who cannot get over her surprise and sadness, is to pass the scholarship exam and go to London. Meanwhile, Mehmet makes a choice that will completely change his destiny. On the other hand, Taner puts into practice his plan to defeat Kağan and Zeynep. Çiğdem, who is trying to hold on to life with the help of Ömer, is unaware of the tragedy that awaits her. Feryat, who learns that Firuze is with a married man, shows a great reaction. Upon this, Firuze explains that she knew the truth when she met with Kağan. After that, nothing will be easy for Firuze and Kağan.

Firuze, who is in custody, thinks that Kağan has complained about her, but the reality is very different. Feryat takes his breath in front of Kağan, who he thinks has ruined his brother's life. Kağan, who got Firuze out from behind the bars, ends his two-year silence when he realizes that Leyla can cause him great harm. He shouts the shocking truth about the accident that cost Leyla the life of her daughters. Kagan does not hesitate to take the step to end his marriage, which is already on paper, in order to go to Firuze immaculately. However, all this does not prevent Leyla's new moves and causes her to grind more teeth against Firuze. Firuze, on the other hand, is confused by the steps taken by Kagan and does not know what to do.

Firuze and Kağan make a promise to each other after hours of reckoning and love. Kağan will appear in front of Firuze after turning a clean page, and Firuze will wait until he returns. Understanding that they cannot break away from each other, it is a matter of curiosity what Mehmet will do. Surrounding Firuze from all sides, Leyla directs her arrows at Feryat this time. He will hit him at the most sensitive point: from his profession... He will slander so much that it will be devastating for everyone. Taner, who cannot turn a deaf ear to Leyla's delusions, makes his last move. He threatens Kagan to return to Leyla over the crime Zeynep committed years ago. Kagan will either give up on Firuze or watch his mother spend her life in prison. Will Kagan be able to get out of this vortex? Will he be able to keep his promises to Firuze?
