"How could you possibly have insomnia?"
"I can only sleep well in my own bed, having trouble sleeping in unfamiliar beds."
Sam actually believed that Angel might suffer from insomnia, as she was the epitome of a pampered heiress.
Obsessive cleanliness, being overly finicky, and needing her own bed to sleep in - none of these traits appearing in her were surprising.
However, Sam couldn't accept this tempting invitation.
After all, this was his own home. If his family found him coming out of this room in the morning, there would be no doubt that his previous explanations to his parents would be seen as lies.
After all, how could two people spending the entire night in one room be just classmates?
Sam withdrew from Angel's grasp, maintaining a distance between them.
