After We Broke Off the Engagement, the CEO Became My Brother.

On the day when the president of the Gu Group proposed to his girlfriend, a strange girl burst into the scene with a yellowed doll marriage certificate. The whole place was in an uproar. Some people scolded her for being wishful thinking, while others suspected that she was here for the Gu family's wealth. The CEO's girlfriend was wary of her, the CEO looked at her coldly, and media influencers rushed to report on this rich farce. But no one knew that she came all the way to Star City not to get married. But to find an answer that has been buried for twenty years. A marriage letter, an old photo, a incomplete diary... As the dusty past is being revealed bit by bit, a shocking secret about family love, lies and redemption is quietly emerging: Marriage letters, old cases of construction site landslides, and huge family trusts have surfaced one after another. When family affection collides with the truth, and when the hypocrite's mask is torn apart, the girl who has been misunderstood by everyone will finally find her own way back.
