Synopsis：The street dance team led by the protagonist A Xing lost to Bian'er in the city street dance challenge. Since then, A Xing has been down and out, drowning his sorrows in alcohol every day. Even Long'er, the girl he likes, looks down on his despondent state. Unable to bear seeing A Xing so dispirited, his good friend Qi'er Wang urges him to pull himself together, reunite his former teammates, and reform their street dance crew. They issue a challenge to Bian'er. Blinded by greed and money, Bian'er sends his own sister Long'er to spy on A Xing's practice routines. Long'er secretly records a conversation with her brother, revealing his scheme. On the day of the competition, Long'er plays the recording in public, exposing Bian'er's actions. She tells everyone that dancing is about expressing personal social value and protecting their shared passion—it should be free, equal, fair, honest, harmonious, and friendly, not a battlefield for selfish gain. Long'er's words earn strong support from all the dancers present.
