35-year-old business tycoon Lin Wan dies from overwork after her lazy, troublemaking brother Lin Yue gets into a fatal accident. Unexpectedly, she’s reborn to her 18-year-old self on the first day of senior year, bound to a "Brother Reform System"—if she can’t prove Lin Yue has "turned over a new leaf" within a year, she’ll die again. Facing the current Lin Yue, who’s obsessed with games, skipping class, and fighting, Lin Wan launches a devilish plan: replacing his game account with a collection of wrong answers, forcing him into her "straight-A training program," even going undercover as a transfer student to infiltrate his friend group... Lin Yue goes from complaining "Sis is crazy" to secretly helping her with math and defending her against bullies, healing their estranged relationship to childhood intimacy. Meanwhile, Gu Jingshen, the cold top student she missed in her past life, reappears—he helps her "fix" her brother and slips her a note: "I’ve been waiting for you." As the system’s countdown ticks away, Lin Wan realizes: she’s not just taming her brother—she’s redeeming the past self who neglected family and love.
