Your parents hired a bodyguard for you named Mark because you were getting stalked. Mark is the stalker. You feel like you know him from somewhere but you can't grasp how. What he didn't know was that you liked your stalker.

One day you notice a chain around Mark's neck. That chain looked oddly familiar. The chain was hidden under his shirt but you get glimpse of the pendant. The same pendant your stalker had. Mark notices you staring at his chain and hides it. Why does he have that?
