One day, a little girl named İncila goes to a big house with her aunt, without knowing that house is going to change her life forever. There, her aunt starts working as a maid, and İncila meets with her closest friend, Naz. Unfortunately, they fall in love with the same man, Mete. Now that he is coming back from London, Naz and İncila's relationship might take an unexpected.

Now that Mete is coming, his mother Gülten must find a way to overcome her fear of leaving the house. İncilay freezes in front of Mete, not even being able to say a word. Fahrünnisa starts thinking that Mete should prepare a prenuptial agreement just in case something goes wrong with Naz's family. Naz loses her mind when İncila messes up the one thing she was supposed to do.

Naz loses her mind again when Mete doesn't arrive on time, which ruins the meaning of that night. İncila has to make an important decision, is she going to accept Mete's offer, or is she going to stay home with Naz. Everyone is waiting for Mete, but it turns out that Mete has already found someone else. When the bell rings, Naz starts jumping for joy, but the same is not true for İncila.

Seeing Mete and Naz kissing, İncila starts feeling betrayed because of that beautiful evening she had with Mete. After that, Naz and Mete have a huge fight, and it is İncila's task to fix their relationship. Just when Mete was about to tell the truth to his family, Naz appears from nowhere to change everything. İncila must find a way to avoid Mete at all cost.

Mete doesn't understand why İncila has been acting weirdly from the beginning. Naz faints again, but Mete knows that she is faking it all the time. Ziya realizes that a prenuptial agreement is necessary for Naz and Mete. İncila must hide under Naz's bed quickly, and unfortunately she might have to spend the night there. Naz wants to meet with Mete's mother, which is a part of her filthy plan.

Gülten isn't happy to hear that Naz and Mete are going to be coming over for lunch. Müberra forces İncila to marry a man she doesn't even know yet without knowing that she is in love with someone else. Filiz loses her mind when Belgin brings a prenuptial agreement with her for Naz and Mete. İncila is locked inside of a small room, just like how her aunt locked her up as a kid.
