After a family tragedy, young Jiang Xiaoyi was adopted by Chen Hailin, a police officer who handled the case. He seemed to have been saved, but he didn't know that the man was the real culprit who killed his father and now his mother and sister. Chen Hailin became murderous because he was jealous of Jiang's father. After many years, he tried to silence Jiang Xiaoyi, and even intended to eradicate Jiang Xiaoyi in the name of "curing the disease." Jiang Xiaoyi's crush Xu Youan accidentally discovered the truth. He knew the danger, but because he loved Jiang Xiaoyi deeply and couldn't bear to break his desire for "home", he chose to fight the devil alone. In the end, Xu Youan died in a life-and-death struggle with Chen Hailin, leaving behind an unspoken love letter. When Jiang Xiaoyi discovered Xu Youan's diary while sorting out his belongings, he learned about Xu Youan's deep love and sacrifice, and fully understood that he had lost everything. With no more worries in the world, he chose to follow Xu Youan and ended this life shrouded in conspiracy and miss with a leap.
Intention: The sacrifice and weight of silent love in desperate situations, exploring the cost and meaning of "guarding".
