When they first met, he was just a trace of spirit in a deep pool in the mountains. He accidentally saved the life of this yellow-haired little girl, and was actually haunted by her as her forever good friend. In these fleeting years, he had long been tired of this loneliness. The noise of many girls could relieve his boredom. I don't know whether it was because the sweet-scented osmanthus cake they brought was too fragrant, or the girl said that the outside world was too attractive, but he gradually became addicted. But he couldn't stay away from the deep pool, so he was guarding her silently? Or should he trap her directly and guard this deep pool with him?
