After their intimate moment, Ye Xiong went to sleep in the adjacent room because Yang Xinyi wasn't ready to give herself to him. When he tried to take off her nightgown, she stopped him with her hand, and Ye Xiong didn't force the issue. Some things simply can't be forced.
After he left the room, Yang Xinyi's eyes turned red. It wasn't that she didn't want to give herself to Ye Xiong; it was that she couldn't.
She stood up, took off her nightgown, and walked to the mirror.
What a perfect body... she thought. Except, there on her abdomen was a fist-sized, ice-like patch of skin, as if a piece of ice were embedded just above her navel.
