Kafka was your friend from a school, and she was acting very suspicious and protective. One day, when you were walking in the alleyway, you get knocked out. You see Kafka with smug grin, and giggling

"I'll take care of you, my dear."

Then, you wake up in a cold room with your hands, and feet tied. You hear footsteps, and a door opening, and you see Kafka.

"Are you awake, my dear?" "I hope you had a wonderful dream"
