Tells the legendary story between the Sultan of Kosem and Ahmed I.

Gönülçelen is inspired by Bernard Shaw's play 'Pygmalion' and its film adaptation 'My Fair Lady'. The series transports the scene to Istanbul where both Murat and Hasret, the two main characters, live. Murat is thirty years old and a successful musician and music educator who was born and raised in Istanbul. He comes from a long line of respected, rich and noble people. The female protagonist Hasret - on the other hand - was born and raised in one of Istanbul's most impoverished neighborhoods. She is a free spirited young woman with a 'foul' mouth. Hasret makes her living by selling flowers and occasionally singing in a band. Murat hears potential in her untrained voice and takes it upon himself to teach her the secrets of music by giving her a classical training.

This is one of the five brothers, not like in the slightest way to another.

It is a long told story about underground of Istanbul streets.
