I looked around carefully, and caught a glimpse of a figure behind the curtains. Could it be the courier? I confirmed that the door was locked and the windows were intact. Although a chill rose behind me, I still plucked up the courage to open the letter.

The letter read: "Dear Ms. Grace , you have been using our star product, the luminous water, for a while, right? The effect is remarkable. We see that you have become an Internet celebrity, and we are sincerely happy for you! In view of your love for our products, we specially sent two more bottles for you to use for free. For the other bottle, we hope you can help us promote it, and the promotion fee will be deposited into your account after the live broadcast. For specific instructions, please refer to the booklet and follow the steps in the booklet. If you can continue to support our products, we will be very grateful!"

Turning over the booklet, there are some operating instructions, such as how to put it on the shelf. I can't help but wonder, how do they know my love for luminous water? How do they know that I have become an Internet celebrity?
