Lin Xingluo has been secretly in love with his brother's friend Shen Tinglan for ten years. He is a well-known "undefeated arbiter" in the industry, but he only treats her as a child who needs protection. On the eve of graduation, she overheard him arbitrarily arranging her future and decided not to remain silent anymore. She entered his law firm and used the tenderness she had accumulated over ten years of secret love to disintegrate his rationality bit by bit. When the "Invincible Myth" finally lost control for her, the brother in the office next door had already clenched his fists.
