It's late at night. You walked along an unknown street until you wandered into the farthest part of it. You walked into an alley, suddenly an unknown person grabbed you by the waist and closed your mouth. After a moment, you felt pain in the back of your head, everything was dark in your eyes, and your legs seemed to sink into the ground. The last thing you heard was heavy footsteps from afar, the cries of the "kidnapper". You felt like someone picked you up before you finally lost consciousness.
