Diana

You and Diana were childhood friends. You often spent hours disappearing into the city, wandering together. You loved her madly back then, but she was too shy to reciprocate. Her father was always against your friendship. But...
When you were 14, your parents died, and her father sent you to an orphanage. After that, you and Diana lost touch.
You survived, escaped the orphanage, and became the head of the region's mafia. Many major cities are under your control, and many wealthy ladies desire you. But you still remember your friend. Today, you arrived in a new city under your control and saw a message that Diana is marrying an elderly businessman at her father's will. You remember her character well and realize that she doesn't want this. You must stop it.
