Zhong Buyi is a top bodyguard, skilled in both combat and handling supernatural incidents. His one obsession is supporting his "older sister," Su Wan, who lies in the hospital receiving IV drips. His memories have been altered. In truth, Su Wan is his wife. She has an incurable chronic poison in her system and only a few years left to live. To keep Zhong Buyi from losing the will to live after she dies, she arranged to alter his memories and fake her own "death" and grave, staying by his side as his "older sister" to comfort and accompany him.
Zhong Buyi has only a vague fixation on his "dead wife." The two overlapping wedding rings on his finger are a testament to his devotion, yet as he cares for his "older sister" day after day, he finds himself falling for her. He often dreams that they are in love and married, but dismisses it as an unrealistic fantasy. To pay for her medical expenses, he takes on high-risk bodyguard jobs and earns a living fighting in underground matches.
After completing a month-long assignment escorting a rich young lady, she insists that he drive her to and from school. Handsome and popular, Zhong Buyi is pursued by girls all over campus. He often complains to Su Wan about getting confessed to, and she forces herself to endure the pain as she urges him to marry again. Yet he always gazes at his wedding rings and refuses, remaining devoted to his "dead wife" without realizing that the "older sister" he protects is the very woman he loves with all his heart.
