As other people have already written in their reviews, Ikimizin Sirri is a remake of a korean drama: Marriage Contract. But what these people didn't write is that it's a really bad remake.
Marriage Contract focuses on the illness of the heroi's mother and the illness of the heroine, while Ikimizin Sirri focuses on the mafia. While Marriage Contract moves us by the growth of the characters, by the pain of a mother who may soon die and leave her little daughter, by the pain of the secondary characters in seeing the suffering of the protagonist, Ikimizin Sirri gives prominence to a silly villain who barely appears in the original version.
The story of Neva's disease is not developed and in the end she is heals out of nowhere (ie the Turkish version has a deus ex machina ending, and precisely one of the things I liked most about the korean drama was that it DOES NOT HAVE a deus ex machina ending, but rather an ending consistent with the story presented, and realistic).
Marriage Contract gives us cliché but very beautiful and valuable lessons: live intensely as if it's your last day, love your family and friends, don't be a bitter person... Ikimizin Sirri gives us a "lesson" (very obvious to anyone) which is: don't be stupid to borrow money from mobsters.
That is, this remake does not come close to quality of the original version.
