The story revolves around the emotional entanglement between the billionaire CEO Chen Mo and Su Wan, a single mother, beginning with lies and ending with sincere love. In order to test the true feelings of his former lover after she had lost her glow, Chen Mo meticulously planned a “fall from grace,” pretending to be a destitute scavenger and reappearing in Su Wan’s life. He witnessed the hardships Su Wan, now a single mother, faced in her daily life and saw the ridicule and torment from their former classmates. Unable to bear it, Chen Mo chose to quietly protect her from the shadows. To fend off the advances of their old classmate Zhang Lei, who was pursuing Su Wan, Chen Mo and Su Wan pretended to be a couple. Seeing that Chen Mo was homeless, Su Wan allowed him to stay in her living room, and he repeatedly helped her resolve various crises. However, Chen Mo’s efforts to protect her were repeatedly compromised by his failure to completely hide his past habits. At a class reunion, his old classmates mocked him, and Zhang Lei’s passionate pursuit of Su Wan further complicated the situation. Whether it was during the reunion where Chen Mo expertly identified fake wine or when, in a crisis, he was able to mobilize impressive resources (like booking an entire hospital), his actions were at odds with his supposed identity as a scavenger. These constant contradictions not only confused and aroused Su Wan’s suspicions but also triggered a series of misunderstandings, complicating their relationship even further. In the end, when all disguises could no longer be maintained and the truth was finally revealed, this reunion, which had begun as a test, faced the ultimate trial of emotions and trust. In the intense clash between truth and lies, Su Wan and Chen Mo ultimately realized that whether poor or rich, only through sincerity, stripped of all pretenses, could they regain the pure love they had lost and searched for over the years.
