Lin Xue suffered the most devastating betrayal of her life on College Entrance Examination results day. After meticulously caring for Chen Wei, who stayed at her home for a whole year, she was repaid with a diary titled "The Pain of Living Under Another's Roof." The distorted facts from the diary were exposed online, turning her overnight into an "evil woman" reviled by the entire internet, and she died unjustly. Given a second chance at life, she directly confronts Chen Wei and her ungrateful family, no longer treating them with equal kindness, and vows never to be taken advantage of again. Lin Xue tears away the hypocritical lie of the 200-yuan monthly living allowance, refuses to advance 10,000 yuan in tuition fees, and puts an end to free tutoring. On results day, when Chen Wei's family brings out the diary again to accuse her in public, Lin Xue unveils her counterattack.
