Whose guardian are you?

Inside a car parked by a curb somewhere in Imperial City,

Han Ye looked at his phone for a second before putting it back into his phone. He glanced at the sleeping teenager sitting in the passenger seat. When the teenager reached up with a bandaged hand and tried to scratch the patch on his right eye, Han Ye immediately reached over to stop him. 

Xiao Zhihao did not protest. He merely mumbled something in his sleep before putting his arm down. It had been a long day for both of them, Xiao Zhihao especially, and he did not even have the energy to act like a child around Han Ye. 

Looking at the sleeping wounded teenager, Han Ye wondered how to break this to Xiao Lei later.
