Sophia hadn't yet experienced Luca getting taken to her bakery by a personal driver.
Seeing the driver wearing a suit and dark sunglasses park the luxury vehicle at the curb and then open the door for the great Luca Morelli, she realized just how different their worlds were. He caught the attention of anyone who walked by, men and women alike.
She had resistance in thinking she belonged in his world, yet as he approached the door, her heart raced. As always, her body responded to him and he didn't have to do anything except exist.
The more these moments occurred to her, the more she started to realize that she wanted to take their relationship to the next level. Maybe the doubts would disappear if she allowed him to explore the physical side of their relationship further.
