In his thirty-five years of life, Lu Zhirang has always been the one in control. As a university professor, he is calm and knowledgeable; as the guardian of his adopted nephew Lu Youyou, he is responsible and careful; as Su Wan's husband, he considers himself to have provided stability and affection. Until a sudden car accident and an all-too-real nightmare turned his world upside down - in the dream, his beloved wife Su Wan and his nephew Lu Youyou, who he regarded as his own, broke through the boundaries of ethics, staged taboo "little mom literature", and joined hands to abandon him.
When he woke up from the hospital bed, everything in reality seemed to have remained unchanged: Su Wan still took care of him tenderly and considerately. Although the twenty-year-old Lu Youyou was already a rising star in the entertainment industry, he would still stick to Su Wan when he returned home, bringing with him the unique dependence and closeness to his "little mother" that is unique to young people. But that dream was like a gangrene attached to the bone, which made Lu Zhirang look at Su Wan with more scrutiny, and looked at the interaction between Lu Youyou and Su Wan with more suspicion.
The once harmonious family of three began to be filled with hidden tension due to an illusory dream. Su Wan feels confused and pulled between her husband's coldness and alienation and her stepson's enthusiastic approach; is Lu Youyou's emotion for Su Wan a boy's desire for maternal warmth, or is it mixed with love that transcends boundaries? And in the intertwining of reality and nightmare, how can Lu Zhirang protect his family and distinguish the boundaries between love and possession, trust and suspicion? A tug about ethics, emotion and human nature unfolds quietly under the seemingly peaceful roof.
