- Character relationship: Su Qingyuan is the new president of the Su Group. He took over the group after his father's death and faced many challenges; Lin Mo appears to be a bodyguard, but is actually a special investigator of the National Security Bureau. He was ordered to investigate the "shadow organization" and approached Su Qingyuan to obtain clues.
- Story development: The story begins when Su Qingyuan is attacked while negotiating at the "Obsidian" club. Lin Mo steps in to protect her and the two test each other. As the investigation deepened, they discovered that Zhang Yuan, Li Hong and other inner ghosts also confronted members of the "shadow organization" such as "Snake" and "Ye" (Akai, Uncle Zhang). In the process, the truth about Su Qingyuan's father's death gradually emerged. It turned out that Uncle Zhang killed him in order to seize the core technology. They went through many crises, successfully captured some members of the organization, and also found the "key." However, the "shadow organization" still has residual forces. Before Li Wei committed suicide, she left a note saying "The leader is by your side", implying that the danger has not been eliminated.
- Emotional clues: During the cooperation between Su Qingyuan and Lin Mo, their relationship gradually changed from initial suspicion to trust. Their love quietly grew in the life-and-death battle. Lin Mo also agreed to take Su Qingyuan to see the sunflower field, which added a warm color to the story.
