Ye Nan was told by her adoptive parents that she was severely allergic to various foods since she was a child. For more than 20 years, she has been eating a light diet and living a restricted life. It wasn't until she came to the house with her boyfriend and tried ordinary meals without feeling any discomfort that she realized that this was a lie told by her adoptive parents who favored sons over daughters and favored their own children. Soon after, the butterfly-shaped birthmark on her leg made her biological mother, who had been looking for a daughter for many years, recognize her. After the truth came to light, Ye Nan completely distanced herself from her adoptive parents and regained a warm life with her biological parents and lovers. The adoptive parents and family also paid the due price for their past actions.
