[Margaret's Perspective]
I thought about it for a long time but couldn't figure it out.
I held it up to the moonlight and saw a little pink light reflected from the bottom of the bottle. I carefully examined the direction of the light source and finally found a little pink water mark that had dried up. It was very light, but it was faintly visible in the bright moonlight.
This discovery excited me. If I could figure out what the pink water mark was, maybe I would find out what secrets Angel had.
And whatever that was, I would prove my worth to Donald. I would do the same things as the assault team. I knew I couldn't tell Donald about this either. I didn't want him to think that I was just messing around. I had to do something concrete to show him.
It was just that I needed to think about this at length. I needed someone reliable I knew to help me with my investigation.
I carefully put both items away in the depths of the drawer.
