Yin Shaojie faced forward, not looking at her. Calm and unruffled, Yin Shaojie picked up the cup and slowly sipped from it. Then he said, "Why would I do it if not to keep you safe? I was afraid that you may get kidnapped again like you did the last time."
He had been tracking her location using her phone. But if her cell phone was destroyed or lost, it would be useless. So this wasn't a very safe method.
As to him sending someone to secretly follow her, he chose to tell her now lest this girl become upset again.
Mu Xiaoxiao thought that it was unfair. "What about you? You can find out my location, but I can't find out about yours. Isn't this unfair?"
With that said, her little hand spread open in front of him.
"Hand over the cell phone, I want to set up location tracking on your cell phone."
Now she would also be able to find out the places he went.
