The Mysterious Kidnapper and False Imprisoner

I can no longer remember how many months have passed since I was abducted and confined here. What is incomprehensible is that the perpetrator makes no demands of me, uses no violence, and does not demand ransom from my family. In the beginning, because they did not wear a mask, I was terrified to my core, convinced they had no intention of letting me leave alive, and I trembled with fear. However, contrary to that expectation, the perpetrator's attitude toward me has always been extremely polite, and they have never even raised their voice at me once.
