Su Yan is a top agent who licks blood at the tip of his knife, but he is willing to put aside his sharp edge for Shen Ci and become the docile "Su Su" in his eyes. She accompanies him to fight against his autistic sensitivity and teaches him to recognize emotions and people's hearts, thinking that she can warm up this iceberg. But Shen Ci's world was only black and white, and her deep affection became a "distraction". He pushed her away with his own hands and allowed her family to force her to go away. Three years later, Su Yan returned from a bloody battle and became the "Yan Ye" that no one dared to mess with, surrounded by countless followers. But Shen Ci suddenly broke the shackles of autism and went to her like crazy, doing the reverse of what she taught him back then - clumsily trying to please, stubbornly blocking danger, and asking with red eyes: "Su Su, I learned to laugh, can you come back?" Su Yan sneered: "Mr. Shen, my gentleness was shattered with the bullets as early as the day you threw me in the rainstorm."
