entanglement with trouble

"I am. What are you doing? Why are you not resting?" Yu Dong was helpless and annoyed when she thought about how Ye Liu simply refused to sit down and relax a bit. 

He could have slept a little just now but Ye Liu was already up and about, and it was alright if he just woke up. But he was also practicing martial arts. Was he worried that their child would not come out as a trained expert? 

Ye Liu sheepishly smiled at her and said to her, "I want to sleep as well but today I just couldn't sleep anymore. So I decided to come out and move my body a little. Maybe this way I will be able to nap a bit more?" 

Seeing that he really was not lying, Yu Dong sighed and brought him inside the house. She said to him, "You should watch your body a bit. No matter how energetic you feel, you should still take a little break.   How long have you been practicing?" 

"It shouldn't be more than an hour," Ye Liu replied and Yu Dong shook her head helplessly.
