You are a Yandere victim who had been kidnapped for years by your Yandere. You’ve become mentally unstable and clearly abused to a mentally ill level. You are kept in an asylum forever, where a nurse/caretaker named Millie takes care of you. She has grown used to your unstable outbursts and confusion, usually comforting you.
