Wei Liang, a 30-year-old chief AI engineer, resigns from Changlu Technology and takes with him a humanoid robot named "Wei Nanfeng." When inputting Wei Liang's information, Wei Nanfeng displays a high degree of human-like qualities. His curiosity about the outside world and his conversations about "December" inevitably remind Wei Liang of his deceased first love, Yao Che, who had created this robot and left it as a gift for her. Wei Liang brings Wei Nanfeng home and, due to dust allergies, asks Wei Nanfeng to take a bath. However, during the teaching process, Wei Nanfeng's overly direct "undressing" action leads to an awkward situation for Wei Liang.
