Xiao Yu was known as the "Soft Bone Rabbit" due to her extraordinary ability to control her bones, granting her unparalleled flexibility and agility. She was a 100,000-year-old soul beast in the form of a cute, adorable rabbit with a soft, fluffy fur coat.
Ever since Xiao Yu had joined Notting Academy, Li Feng had been inexplicably drawn to her. He couldn't explain why, but something about her innocent charm and her caring nature had captured his heart. Despite knowing the original story, where Xiao Yu falls in love with Tang San and sacrifices herself for him, Li Feng found himself falling for her even though he tried to suppress these feelings.
Li Feng and Xiao Yu spent a lot of time together, and their emotional attachment grew stronger each day. Xiao Yu saw Li Feng as not only her dear brother but also a lover. One evening, as the moonlight bathed the room, Xiao Yu shyly handed Li Feng a precious comb that belonged to her mother, entrusting it to him as a symbol of their bond.
As their bond deepened, Xiao Yu couldn't help but worry about her true identity as a 100,000-year-old soul beast. She feared that if others found out, it could put her and her loved ones in danger. Li Feng reassured her that he would protect her no matter what and that her identity wouldn't change how he felt about her.
As time passed, Li Feng noticed Xiao Yu's distaste for Tang San, who was often trying to get closer to her. Xiao Yu's anger towards Tang San was apparent, and it often led to heated arguments between him and Li Feng.
Li Feng couldn't stand seeing Xiao Yu uncomfortable and upset, and this only fueled his determination to protect her and be the one by her side. He began to develop a rivalry with Tang San, who seemed to be interfering in his and Xiao Yu's relationship.
