It tells the story of Ji Xiong'er, who grew up in the Ji family, accidentally learned that she was the wrong child, and that the real daughter of the Ji family was Shen Xinxin, an ordinary person. The eldest son of the Ji family, Ji Tanlin, is an indifferent boss with severe mysophobia and allergies when touching women. He is immune only to Ji Ling'er. He has been deeply attached to each other day and night, but he suffers because of his status as "brother and sister".
The moment the truth was revealed, Ji Tanlin's suppressed emotions finally found an outlet. While suppressing his joy, he launched a secret pursuit in the name of "brother". Ji Ruoyi, the second youngest son of the Ji family (the unruly race car driver), and Ji Huochen, the third youngest son (a top star) of the Ji family, have no grudges. They still dote on Ji Cong'er as a princess and tell her with their actions: "Blood is never a bond, love is."
Shen Xinxin's appearance caused temporary disturbances, but it did not shake the Ji family's cherishment of Ji Xiong'er. The story revolves around the emotional pull and family warmth after identity dislocation. Watch how Ji Tanlin breaks through his guard and transforms from an iceberg into a dedicated "loyal dog"; watch Ji Liao'er find himself in the fog of his life experience, and finally join hands with his lover and family to write a warm chapter that has nothing to do with blood ties but only love. Among them are the heart-stirring secrets of a boss chasing his wife, the daily healing of brother, friend and sister Gong, and the in-depth exploration of growth and self-identity.
