In the middle of the night, Xu Xiaoyan turned over in her sleep, feeling as if something was missing by her side. She reached out to pat next to her and, finding it empty, she opened her eyes: "Yan Xiaofei…"
Yan Fei, who was busy, quickly turned his head: "I'm just reviewing some material. Go back to sleep!"
"What time is it?" the girl asked groggily.
"Only a little after three. Keep sleeping!" Yan Fei glanced at the time and said.
"Do you need help?" The girl suddenly became more alert. "What material is so urgent?"
"It's not that urgent, I just can't sleep, so I'm keeping myself busy. You should really sleep." Yan Fei came over, pulled up the quilt to cover her, and inevitably slipped his hand in to take a little advantage.
