The social fear girl Bai Rongrong accidentally traveled to the world of spirits and was bound to the "Heart Voice Resonance System". Her goal is to understand the heart of the cold and aloof Mr. Fox, Mo Chen. The system revealed the "lonely moon on the mountain, and the chill in his bones" in his heart, giving her a desire to understand. Faced with the appearance of the iceberg and his own social fear, Bai Rongrong used his "mood soothing" ability to carefully test and melt the ice in Mr. Fox's heart little by little. However, the Wanling World's prejudice against the Fox Clan, the Peacock Master's provocation, and the power struggle within the Fox Clan put their relationship facing many tests. When Mr. Fox was in a family crisis and on the verge of mental collapse, Bai Rongrong exhausted his mental power and saw the secret knot of his childhood through "spiritual echoes". She stood up bravely, exposed the conspiracy, and defended him. Not only did she help him get through the difficulties, but she also sublimated the relationship between the two and reached "complete resonance." Mr. Fox opens his heart to her for the first time and shows affection for her. Just as the sweetness is heating up, a greater crisis has arrived! The fox shadow joins forces with the wolf clan and aims directly at Bai Rongrong. The world of spirits is once again in turmoil, and a race war is about to break out! Can the Social Fear Rabbit join hands with Mr. Fox to overcome the difficulties in troubled times?
