As a non-staff employee of the underworld's "Psychic Restoration Department", Su Ye's KPIs are always very different - for example, making the young CEO, who was riddled with violence due to the shadow of his youth and destined to die young, feel the warmth of the world again. The "efficient plan" recommended by the underworld was actually a human marriage agreement. So, as a professional psychological counselor and part-time civil servant, she took over the most difficult case in her life and her "husband". When he was trembling in nightmares, she quietly comforted him with her professional skills; when the past bullying came back, she showed her a contract: "Cooperate, I will heal your heart, and you lend me your status." Shen Ru never thought that this woman who came for the "mission" would become the only light shining into his dark world. And she never expected that this contract that started with KPI would eventually require her to use all her sincerity and even give up her special identity in exchange for his life-long peace and joy.
