Cheng Yuanzhou and Su Wanqing have been married for five years, working diligently to establish a home and building a stable, prosperous family. After his wife's first love, Lu Zean, returns to the country, he deliberately packages a high-quality persona to disguise himself, frequently interfering in their marriage, intentionally provoking conflicts, and challenging Cheng Yuanzhou. Deeply trapped in the filter of her old romance, Su Wanqing disregards years of marital affection, repeatedly favoring the other party and even secretly taking out family savings to support Lu Zean. Repeated exhaustion leaves Cheng Yuanzhou completely cold-hearted; he investigates the truth and properly secures his personal assets. After Lu Zean's false persona is exposed, Su Wanqing is filled with remorse, but their relationship has long since completely shattered. In the end, they part ways amicably, and Lu Zean also departs in dismay.
