The series can be divided into two parts-13 episodes based on the show description, and 2 episodes of a completely new series, different setting, no real explanations given for this huge change. The main character, at first, has a deadly disease and is dying. As the series progresses, the deadly disease becomes manageable. In the last two episodes, the disease is non-existent. The male lead somehow died off screen and is going by a different name now. If we can call Mahir a protagonist, since his rival Ali seems destined to end up with Cihan. She always goes back to him, no matter what. Cihan's mother, the woman that is supposed to play a huge role and fight against her daughter's disease, died off screen too. Mahir and Cihan changed majors before ep. 14, off screen of course. The last two episodes are truly disappointing, the ending is a huge fail. What was a touching story about struggle and love for life, becomes a cliche series about two people''in love'' working in a huge company. The character profiles are changed-the simple, funny, naive students become cold businessmen over night. No explanation is given. It seems that the executives got tired of their own story and tried to rewrite it, failing miserably in the process, then abandoning the faulty product. My advice-If you decide to watch this show, watch only the first 13 episodes. Episodes 14 and 15 should belong to another show.
