One morning, a little girl, Mine, is left at the door of Münevver Hanım's mansion by her older sister Yasemin without any explanation. Münevver Hanım, who has been longingly waiting for her children whom she has not seen for years, is confused about what to do in the face of this uninvited guest. Her assistant Halil and his family try to find out who the child is. However, the answer is very close at hand. Mine's older sister Yasemin started working at the same hospital as Halil's doctor son Burak. Burak fell in love with Yasemin the moment he saw her, without knowing who she was.

Münevver Hanım wants to have a DNA test done to see if she is Mine's grandmother. Burak takes the hair samples to his friend at the hospital laboratory. Münevver Hanım treats the little girl, who she does not yet know, very harshly because she thinks that a gang of thieves left her there. People in the neighborhood talk about the little girl who came to Münevver Hanım's mansion and wonder who she is.

She tells Halil to find her daughter Pakize as soon as possible. Some of Mine's actions and words remind Münevver Hanım of Pakize. Burak realizes that he is not the only person in the hospital who likes Yasemin, and that Kerem is not indifferent to Yasemin either. A mysterious man comes to the hospital and asks about Yasemin. Although his surname is different, Yasemin is scared when she sees this man and Şengül is suspicious of this situation. While Yasemin is visiting her sick mother, who she has hidden from everyone, someone sees her.

When Kerem sees Yasemin crying next to her sick mother, he thinks she is a good-hearted and emotional person. Kerem and Yasemin's closeness disturbs Burak.
