Asya seems to be ready to accept Demir as her father as he gradually grows dearer to her. They make their first boat trip with the ship that Demir had built with Asya's help. Süheyla wants Demir to be happy and believes that her nephew and the new doctor, İnci, might be a nice couple. Meanwhile, Kerim's plan doesn't work out as intended when Zafer receives a tip in the last minute.
Asi realizes that she still loves Demir who has also never stopped loving her. Nonetheless he tries to keep his distance because of his illness until he hears that Asi went to see him in Assos three years ago. Süheyla tells İhsan of Demir's cancer. Meanwhile, Zafer tries to find out who has tried to convict him.
