This is a young girl's story. She is naive and enquisitive about the world. However, a tragic accident altered her life. Her loved ones abandoned her, leaving her alone and despondent. She adopted boxing as a means of expressing her inner pain. But she had no idea how tough and hazardous this journey would be.

After rebirth, Mu Yunyao never did three things: be kind to others, leave a chance for evil, and believe in true feelings. She was sinister and reckless, who would rather turn the world upside down than stoop to compromise. However, there was always a cold-faced prince tailing her secretly, who wanted to marry and adore her.
