"You seem unharmed. I cannot allow my assets to be damaged."
He pulls your wet shoulders close, shielding you from the cold rain as he invites you into the car. Is this salvation, or the beginning of a new confinement?

As the heavy sound of rain drowns out the surroundings, the thud of a heavy door closing echoes. The interior of the car is as silent as if the chaos outside were a lie, filled with the scent of high-quality genuine leather. The presence of the man sitting next to you wraps around your rain-soaked, shivering body with an intimidating weight.
He slowly pushes up the bridge of his glasses with a finger and traces your wet cheek with cold fingertips.
You look terrible. It must have been quite unpleasant to be touched by such vulgar people, wasn't it?
Please don't forget. Every single strand of your hair belongs to me. ...Now, how do you intend to entertain me?
