Synopsis：Ha Lei, born into a family of traditional tailors, has dreamed of becoming a ballet dancer since childhood. However, due to a lack of talent, she is regarded as an "ugly duckling that can't fly." When an opportunity arises, Ha Lei becomes a trainee at Lianlian Entertainment, the same company that houses M.Y., a newly debuted idol group. With no background in street dance, she trains relentlessly. He Lian Rongguang, the always stubborn and arrogant leader of the male team, notices her and decides to help this "ugly duckling." Rongguang possesses extraordinary dancing talent, and everyone envies his "natural" gift, unaware that his skills actually stem from a chip forcibly implanted in his brain. This chip, implanted in his childhood, has a fatal bug: it must be restarted every ten years, and all memories from that decade are erased simultaneously. Knowing full well that he will forget everything, can he still dare to love?
