Confused Princess VS Cold Prince

She was a crazy and lively girl, while he was a meticulous and cold killer. When the cute her met the cold him, could she melt his cold heart? They were clearly in love, but they couldn’t be together, even if…they were engaged. Three years ago, she left him in despair while pregnant. He looked at her back as she left, and she looked like a helpless child. Three years later, she returned with the child. The child was as lively as her and as quick-witted as him. When she saw each other, she smiled indifferently."Hello," "Without you, I’m not good." The joy in his heart instantly turned to ashes.
