When she met his three lives, she exchanged her three hundred years of practice for his peace in the three lives. She said she was just repaying the favor. She protected him from life to life, and in the last life, she understood a story that the big monsters often told when she was a little cat demon: A silly demon fell in love with a human... Someone asked her, did she regret it? She shook her head, looking at the familiar him who was still smiling like a spring breeze and wearing a long gown embroidered with bamboo. She said: "How can I regret it? No one has given me the happiness in these three lives. In the end, I owe it to him. Now I have finally paid it off, and I am happy..." When she turned around, tears fell down.
