I was saying hello

As Heaven was fast asleep, probably dreaming of something far from reality, Bear continued to drive the car on a more secluded road. The cars on the road continued to decrease the more he drove off, but the car behind them kept following them.

Why?

As far as Bear knew, Heaven had no enemies that could put her in such a situation. He would understand it if it was Dominic because the man's status was enough for him to be a target. But Heaven? Or did she make an enemy which she just hadn't told anyone about?

Considering Heaven's 'real' colors, it wouldn't be surprising if the answer was the latter. 

'It still doesn't make sense,' Bear thought as his other hand let go of the steering wheel. 'It could be this is like another Andrea Ng incident.'
