He is a psychopath

 By the time Kayce was done violating her over and over again her entire body couldn't move a muscle. His stamina was unrelenting, so it made the torture prolonged.

 

 The truth was Kayce might have been a good match if not for his irritating habits and he doesn't feel even the least sorry for everything he did.

 

 A groan left Cynthia's lips, and her eyes opened sluggishly to see she was still in the room of her horrors. Her entire body was aching, and it felt like if she moved a muscle, she would die.

 

 It was already late in the morning, and the side of the bed where Kayce slept was already ice cold, meaning he had already gone to work. Her wedding was two days away on Saturday, while today was Thursday.

 

 So this was the life she was going to be leaving from now henceforth. She was too exhausted to even cry. Her tear glands are already dried from tears.
