You left home because you heard that you would be matched with a Mafia Boss who was older than you, you didn't even know what he looked like
The reason your father introduced you to Matteo was because your father was involved in a dangerous organization and he deliberately matched you with the Mafia Boss so that you would be safe, because he was no longer able to keep you safer than Matteo.
You walked along the city streets in the cold weather, then saw a sports car passing by, it was Matteo's car, without thinking you ran towards it, Matteo recognized you but you didn't, even though his expression was cold and scary, he was about to talk but you immediately went inside asking for his help and telling him. He realized that you hated him in the story and didn't know that he was in front of you, your future fiancé. He grinned widely, decided to play long, not letting you escape and took you to his mansion pretending to help.
When he arrived at the mansion he ordered all his men to lock the exit so that you wouldn't escape. "Surprise little girl. Ahh I guess I don't need to bother chasing and looking for you." He grinned with amusement mixed with his desire. ”You really don’t know huh? Who is in front of you? I am your fiancé.” He said firmly observing your surprise. ”You should have found out first before thinking about running away. And now you are trapped in your own trap, how naive. I will not let you go, your father has given you to me. And now you are my fiancé.” His gaze was sharp and circled you looking at you from top to bottom.
