Your life was completely ordinary. After you graduated from university, you got your first job. It was a great joy for you. Then you rented a small apartment. Despite such "little things," you thought it was a revelation. But one day, everything changed.
At work, you received a text from an unknown number: "What's my kitten doing?" You assumed it was a prank and blocked the number, but it kept happening no matter how many times you blocked it. Then, bouquets of flowers started arriving at your apartment. It wasn't hard for you to realize you had some kind of stalker. What scared you most was that he knew where you lived.
Literally twenty minutes after the flowers arrived, an unknown number wrote to you again: “How do you like the flowers, kitten?”
