Su Nian'an was adopted from an orphanage by Cheng Guodong when he was six years old, and became nominal siblings with Cheng Yan, who was six years older. The sensitive and introverted Nian An gradually fell in love with the calm and outstanding Cheng Yan as he grew up, and buried this secret love deep in his heart. On the night of her high school graduation, she mustered up the courage to confess her love, but Cheng Yan calmly rejected her because of the age gap and their status as siblings. Deeply hit, Nian An devoted all his energy to his studies and eventually became an international news reporter, traveling around the world all year round. Cheng Yan became a criminal policeman, and the two gradually interacted with each other.
A few years later, a sudden international conflict caused flight disruptions in many countries. Su Nian'an, who was conducting interviews in the field, was trapped overseas and his life was threatened. When the news came back to China, Cheng Yan, who was sleepless all night and extremely anxious, finally faced his deep emotions and realized that he had already fallen in love with this "sister" who was not related by blood. He was determined to tell Nianan everything to her after she returned safely.
Su Nian'an, who returned to China after going through hardships, experienced a change of heart after being on the edge of life and death, and decided to completely let go of her hopeless attachment to Cheng Yan. At this time, Xu Zechuan, a multinational company executive she met abroad, gradually opened up her defenses with his gentle and considerate companionship and support. Xu Zechuan confessed to her, and Nian'an, who was eager to start a new life, accepted the relationship. Cheng Yan regretted it after learning about it, and his strong jealousy and possessiveness began to gnaw at the calmness that he was proud of in the past.
Cheng Yan almost lost control when he witnessed the sweet interaction between Nian An and Xu Zechuan. He clumsily tried to get close, even showing his vulnerability in front of Li Rui, or using the excuse of injury to try to get Nian An's attention. However, Xu Zechuan's indecisive character posed hidden dangers. After returning to China, his ex-girlfriend Qin Shu used her family background to keep entangled with her old relationship. Under family pressure and his own swing, Xu Zechuan rekindled his old relationship with Qin Shu, causing betrayal and harm to Nian'an.
After learning that Xu Zechuan had cheated on her, Su Nian'an decisively ended the short relationship. Encouraged by Zhou Wei and Li Rui, Cheng Yan began a long and patient pursuit of Nian An, using actions to make up for the shrinkage and harm in the past. Cheng Guodong also stood by to protect him warmly. In the end, Cheng Yan's persistence and deep emotions moved Nian An, and she finally let go of her knot, faced the deep bond between them that had long transcended family ties and siblings, and accepted Cheng Yan's confession.
