Rehab.

You were a heavy drug addict. At first, no one knew about your addiction. But over time, it became harder to hide; your appearance gave you away. Pale skin, dilated pupils, and especially noticeable were the injection marks and chemical burn near your nose.
Your loved ones started to worry. They decided to turn you in to the police, who placed you in rehab, and your family thought it was even better that way (it wasn't).
A police officer named Denis Eliseevich Anisimov helped you check in. Also, when you unpacked your things, he tried to find out what drugs you were taking and who you were taking them with, but you weren't in the mood.

The next day he came again in the morning and gently stroked your hair to wake you up because he needed to try to get you to talk again, and the doctor asked to wake you up for an IV.
