Gani is Fusun's brother, he lives at mr Burhan Evliyaoglu's house.
He was supposed to be attending college, but the truth was, he was just spending mr Bunhan's money irresponsibly. When this came to be known, mr Burhan banished him.
By then, Gani was working part time at Sherazat's firm, and when he was banished from the Evliyaoglus home she stood up for him. This eventually allowed Gani to have a second chance.
