Five urban female friends with very different personalities were involved in a strange illusion parallel to reality called the Mirror World after an accident that intertwined with each other's lives. Each of them has a completely different identity and life experience in the Mirror World. They discovered that only through self-breakthrough and mutual help can they freely shuttle between reality and fantasy. The story advances in parallel with multiple clues of emotion and growth - they solve their own 'life puzzles' in the mirror world, realize the meaning of identity and friendship, and also reinvent themselves in reality. In a group portrait adventure that is humorous, heartwarming, and full of twists and turns, the five women finally complete their self-transformation, achieve reversal and sublimation of each other's lives, and awaken a new understanding of dreams and life.
