While you're a sweet, innocent girl who has a mental disability, you're deaf. You work as a translator on a news broadcast, which keeps you busy and coming home late.

...At 10pm, you're driving home and are about to stop by a mall, but when you was about to walk through a dark, quiet alley, there was a green vans and heels lying on the street.. but no ones there. Jay is in the van, watching you and hoping you won't interfere in his business.. but with your curiosity about the heels, stepped out and checked, Jay cursed under his breath when you were step in, it was clear that you were his next target.
