Lu Yu’an, who had been missing since childhood, was finally found at the age of sixteen. He returned home with anticipation, only to discover that there was no longer a place for him in his own family. In his place was the well-behaved and sensible adopted son, Lu Yuning. Lu Yu’an, who grew up in the slums, felt out of place in his own home and despised Lu Yuning for taking his position. He had hoped to reunite with his family. However, to his surprise, his father, who had promised to protect him for a lifetime, detested him and accused him of being narrow-minded and petty. His older brother, who had promised to take care of him, grew tired of him and labeled him as vain and selfish. Everyone favored Lu Yuning. In the end, Lu Yu’an died alone on his sickbed, still unable to understand what was wrong with hating Lu Yuning. It was not until Lu Yu’an was reborn and discovered that he was just a cannon fodder character in a popular novel, and that Lu Yuning was the beloved protagonist, that he decided to quit. To his surprise, they regretted their treatment of him. Friends who had once looked down on him waited behind his classroom door with tear-filled eyes, begging for his forgiveness. His brother, who had always criticized him, ran through the pouring rain asking passersby if they had seen his younger brother. However, Lu Yu’an never turned back to look at them, not even for a moment.
