His mother is critically ill, and the poor boy Lin Wang has no choice but to contract marriage to the president of the Mu family. The female president Mu Xin is as cold as ice and only wants to complete the task. But he refuses to accept his fate: he quarrels with his relatives at the family dinner, protects his wife in the business war, and throws sulfuric acid to protect her. Every time he tries his best, the iceberg cracks. A year later, the twins were born and the contract expired, but Mu Xin tore up the documents and hugged him, "If you become a full-time employee, I want you to be my coward for the rest of your life."
