Seven years ago, Gu Xingwan stabbed her biological father and was imprisoned; five years ago, Yan Jin waited for her at the prison gate with an umbrella, only to learn that she had already been released. Seven years later, they meet again. Gu Xingwan stares blankly at the legal tycoon Yan Jin, who claims not to know her and that they are already engaged. Gu Xingwan chooses to remain silent, and no one knows that she had given birth to Yan Jin's child while in prison. The past entanglements and unspoken secrets have become the deepest longing in her heart.
