Liu Xin, a self-made architect, thought he had married the most perfect wife in the world, Su Wan - she was gentle and considerate, diligent and thrifty, and kept her family in order, making her a safe haven in his tiring life. However, an anonymous text message from an unknown number and a piece of luxury jewelry that did not belong to Su Wan, like pebbles thrown into a calm lake, broke this seemingly stable happiness. With Liu Xin's secret investigation, his wife's "gentle and virtuous" façade peels off layer by layer: she hides a complicated past, a mysterious social circle, and is even inextricably linked to an old case. Every time a lie is exposed, it is accompanied by deeper secrets and more bitter betrayal. Liu Xin struggles on the edge of love and hate, not only to uncover the full truth about his wife, but also to face the cruel game about human nature, interests and redemption behind this marriage.
