Zhen Keyi (Dong Qing), a new employee of Wuji.com, accidentally woke up Zhen Jun (Chen Zheyuan) in the sleeping cabin. Because Zhen Keyi looks very similar to Zhen Jun's brother, Zhen Jun regards her as the only life-saving straw in this strange world, so he holds on to her tightly. In desperation, the kind-hearted Zhen Keyi had to start living with Zhen Jun. At the beginning, Zhen Jun, this "old antique", was very different from Zhen Keyi in terms of personality and living habits. The two had repeated misunderstandings and their relationship was very tense, but as time went on, Zhen Keyi discovered the valuable qualities of Zhen Jun, and the two hearts gradually narrowed the distance. However, when Zhen Keyi learned that Zhen Jun was actually the "ancestor" in her family tree, she hesitated about her feelings.
