Sixteen years ago, Chu Nana was abandoned by her biological parents because she was a girl, and was raised with great difficulty by her adoptive father. Sixteen years later, her biological parents, whom she had never met, suddenly appeared, solely because her biological younger brother was suffering from severe aplastic anemia, and Chu Nana was a complete bone marrow match for him. To force her to donate, her biological parents made a scene at the school gate, hung banners to spread rumors, went on a family show to incite cyberbullying, and wantonly trampled on her dignity and privacy. Chu Nana did not let herself be kidnapped by blood ties and morality, quietly preserving all evidence to fight against malicious coercion. She did not agree with the actions of her biological parents, yet pitied her innocent, sick younger brother.
