Don't Be Afraid, I'm a Demon

I was a human a long time ago. I took poison for her and became a nameless harpy. She said that she would never let me down if I did this for her. She said she loved me, and I believed her. But then she said she was scared, so I let her go. She blinked and didn't dare to speak, for fear that she would not be able to suppress her demonic nature and make bird calls. The seasons change and animals hibernate. I am the only one left hovering in the sky, thinking about her lies and spending the long night killing this boring time. I just flew and flew, I don't know how long I flew, and I couldn't remember the way back. It wasn't until later that I met a fox demon who was quite famous before she lost her magic power. She was injured and I didn't know how to treat her, so I had to carry her to a cave to recuperate. When she woke up, she said she wanted to repay me. I quickly said no, she was sitting next to me. He showed an incredible smile and said to me: "Don't you want to turn back into a human? The evil spell in you is not deep and I happen to know how to remove it. Now that you have saved me, I will return your love." I was in a daze for a moment. I almost forgot that I was a human. I was almost used to being a monster...
