Gabriella Sfenza de Feo is a Genoese merchant from a noble family who was widowed very early and continued to run the family business. She trades in the port of the Ottoman Empire.
Once her cargo was unjustly arrested, and the stubborn woman, seeking justice, turned to Mahidevran and Mustafa for help.
From the first episodes, it would seem that a spark ran between Mustafa and the signora, but their relationship did not go further than affairs. And after Mustafa helped Gabriella return her cargo, he began to pay less attention to her.
From the story of the senora herself, it turns out that she is from a noble family, but from her relatives, except for her son, she has no one left. Many years ago, her ship was attacked by pirates who killed Gabriella's husband and kidnapped her younger sister.
Since then, the signora, without losing hope, was looking for her sister, and later she was told that Lucretia was in the shahzad harem.
Despite Mahidevran's displeasure, Gabriella often visits the harem, hoping to find her sister there, and from one such visit, she finally recognizes her in one of the slaves.
The girl in the harem was given a different name - Rumeis, and she does not remember her past at all. However, she had a birthmark on her arm.
Mustafa, having learned the reason for Signora Gabriella's stay, granted her sister freedom, but Rumeisa refused to leave the harem, hoping to one day become the beloved concubine of the Shahzadeh.
Signora Gabriella could not go against the will of her sister and Shahzadeh, and she had to leave the palace and Manisa.
Rumeisa, having proved her loyalty, becomes Mustafa's beloved concubine and even becomes pregnant from him. However, on one of the trips to sanjak, the young people are attacked by Hürrem mercenaries.
Rumeisa notices the shooter and covers the shahzade with his body, thereby saving his life, having lost his own and future heir to the Ottoman Empire.
