"Good morning, Darling~" 

As soon as Yuan opened his eyes, he was greeted by his mother's beautiful face. She had a sweet smile on her face.

"Good morning, Mom." Yuan said, then he asked, "It seems that I woke up late today because of our 'Night Activity'. When did you wake up, Mom?" 

"Well, I woke up about half an hour ago." She replied as she snuggled in his chest while hugging him tightly.

Yuan smiled seeing his mother's behavior and caressed her cheeks with his fingers, he understood very well what his beautiful mother wanted from him. However, he won't give it to her just yet.

"Why didn't you wake up then? Since you're awake for a long time you should've wake me up as well."

After hearing this, she smiled and planted a kiss on his cheeks, and said, "Well... You look very cute when you're sleeping so soundly, so I couldn't bring myself to wake you up." 

"So, does that mean you stared at me the whole time I was asleep?"
