Ren Xiaoxian, who has loved dancing since she was a child, like all people who love dancing, dreams of becoming the protagonist on the stage one day, but she has been stuck in the stage of a "little celebrity" for many years. Fortunately, Positive, optimistic and full of positive energy, she doesn't care whether she can succeed or not. She only cares about being able to dance when she wakes up every morning and having delicious food when she opens her mouth.

Her career was not as smooth as she imagined. She thought that happiness was just around the corner, but she didn't expect that fate would play another big joke on her. The wedding and honeymoon with Huang Lezong was originally a happy and joyful event, but unexpectedly, the accident came so suddenly. Huang Lezong suddenly disappeared mysteriously while surfing. Sad, she returned home but failed to get the understanding of her mother-in-law, Mei Chaoying. The deeply hit Mei Chaoying determined that Ren Xiaoxian killed her son in order to seize the "authentic" family martial arts business.

As a result, Ren Xiaoxian became the biggest threat to Mei Chaoying, and she decided to drive Ren Xiaoxian away quietly. However, after a failure, kind-hearted Ren Xiaoxian not only became more convinced of Huang Lezong's feelings for him, but also moved into Mei's house to live with her mother-in-law. Ren Xiaoxian's move made Mei Chaoying feel helpless, so she made things difficult for Ren Xiaoxian in every possible way, and even tricked her, who didn't know Kung Fu, to face the martial arts champion who came to kick the gym, but she didn't expect Ren Xiaoxian to win a big victory. Huang Shulang, who was suppressed for having an affair abroad and had to return to China, has coveted Mei Chaoying's family martial arts business "Authentic" for a long time. When he failed to succeed, he planned to secretly take action, which led to many crises in "Authentic", but Mei Chaoying reluctantly supported it. In times of crisis, Ren Xiaoxian still took care of her devastated mother-in-law without hesitation. Later, the amnesiac Mei Chaoying developed a long-lost boxing skill in the world. In order to retain Ren Xiaoxian, she forced Ren Xiaoxian to take over the "authentic".
