Su Qingyuan unexpectedly is reborn, happening to return to the crucial turning point of her life's destiny. At the banquet, her younger sister Su Yuran uses the same old trick again, publicly framing her for intentionally destroying a precious necklace, attempting to ruin her reputation. In her past life, she was cowardly and forbearing, suffering all kinds of grievances and betrayal. In this life, Su Qingyuan is calm and composed, relying on meticulous logic to reason step by step, exposing her sister's self-directed and self-acted conspiracy on the spot, from then on refusing to step back, counterattacking step by step, and launching a thoroughly satisfying revenge against all her enemies.
