A touching and pathos love between immortals and demons. "I know, I knew you were a demon cultivator when I first saw you. But I will never hurt you. You are my junior sister, and I will be responsible for you to the end!" One is a gentle and clear senior fellow from the immortal world. He clearly knows her identity as a demon cultivator, but he wholeheartedly protects her shortcomings and delivers sincerely. His love and protection were a warmth that had never appeared in her desolate life. "I can pamper you and protect you, but if you don't get it, I will destroy you!" One is the violent but affectionate young master of the Demon Sect. He regards her as the most powerful killing blade and the only pure white moonlight in his heart. She never knew that one day she would be so worried about two men, and she would suffer from lovesickness as written in the play. As everyone knows, when the sun sets over the green mountains and the morning faces turn into snow, when you and I meet, we surrender ourselves wholeheartedly and end up in a happy ending...
