It's Your Daughter

Song Xin'ai was rubbing her sore neck as she unlocked her locker while yawning. She clearly was tired and severely lacked sleep.

"Professor Song, you pulled another all-nighter?"

Song Xin'ai looked up at the person who spoke who was a rather young researcher on their team and only joined the research center about six months or so.

He was even younger than her own son and that's why she always looked at him very kindly. 

"Why don't you care about yourself?" The young man sounded rather vexed and helpless as he spoke. "At this rate, you'll get sick again. Why do you keep pushing your body?"

"Harry, you're here early again?"

"Professor Song, don't change the topic."
