Lin Xi discovers a creepy pattern: in every exam, her younger brother Lin Hao's score is always precisely ten points higher than hers. This consistently crushing score makes her brother showered with favoritism and praise, while she lives year-round in his halo and her family's neglect. To test her hypothesis, she intentionally takes a sick leave and misses the exam; lacking her score as a source, Lin Hao's exam performance collapses, plummeting directly by two hundred and fifty places. She finally becomes certain of the truth: her brother's high scores were never born of talent, but grew attached to her instead. With the maximum college entrance exam score being only seven hundred and fifty points, she resolves to break through her limits and personally tear apart the academic star halo her brother stole.
