Romeo, also known as Rossi, was bought from Luini by a man named Marchelo Rossi. This individual is known for being a heavy drinker and was once easily influenced by his wife Edda, who was selfish, bossy, and overweight. However, he later gained the courage to speak up for what he believed in and took steps to improve Romeo's life in Milan. To Romeo, Marchelo is like a second father.
Marchelo has one son named Anzelmo and one foster daughter named Angeletta. The latter was entrusted to him by Lady Isabella Montovani when she was still an infant. He cared for her until the countess accepted her as her granddaughter.
