My Daughter Refuses to Donate Marrow

My Daughter Refuses to Donate Marrow Plot:

Single mother Su Min is suddenly diagnosed with leukemia, and the only matching bone marrow donor is her 15-year-old daughter Sang Sang. But when she begs Sang Sang to save her with tears, Sang Sang refuses without hesitation. Relatives label Sang Sang an ungrateful wretch, and Su Min sinks into despair—until she stumbles upon Sang Sang’s phone, which holds a DNA report revealing Sang Sang is not her biological child at all! It turns out Sang Sang learned she was adopted three months ago, and Su Min’s so-called “life-saving” plea is actually a request for her to donate marrow to a “biological daughter” she’s never even met. When the truth comes to light, is Su Min’s tears born of guilt or calculation? Is Sang Sang’s refusal a grievance-fueled counterattack or a sober escape?
