The fake daughter Si Nian was thrown back to the Poor Star by the real daughter Lin Sisi to take the blame. She was forced to marry Pei Yan, a retired mecha commander who was rumored to be cold-blooded, and at the same time take care of the five oil bottles he left behind. Facing the target of the reborn Lin Sisi, Si Nian relied on his tenacity and wisdom to move from a contractual marriage to a two-way relationship with Pei Yan in the border galaxy. Not only did he train the children to become talented teenagers in the Interstellar Academy, but he also joined forces with Pei Yan to build a business empire covering the border areas. When Lin Sisi thought that Si Nian had "no children", she witnessed the sweet scene of Pei Yan escorting his pregnant wife on the news, and she completely collapsed - not only was Si Nian pampered, but he was about to have a child for the two of them, while Lin Sisi's wealthy marriage was already riddled with holes.
