For the urgent ten million, Su Qingyan took on a bizarre job - becoming the exclusive "lie connoisseur" of the empire's president Fu Yunting. She can see through all hypocrisy, while he lives surrounded by lies. He regards her as the sharpest knife, and she regards him as the most generous donor. A deal, everyone gets what they want. She overcame obstacles for him, identifying falsehoods and preserving truths, but she didn't know that she had already stepped into the tender trap he carefully weaved. When she finally saved enough life-saving money and wanted to escape, the cold and ascetic man blocked her way, his eyes filled with passion that she couldn't see through: "Su Qingyan, can you tell if the 'I love you' I'm saying now is true or false?"
