Shang Yechu has been reborn. In her past life, she was an obese good-for-nothing despised by her entire family, dying a miserable death on the street after being completely exploited. In this life, she binds with the Weight Exchange System, shedding sixty kilograms of excess fat in exchange for an ultra-high IQ of 138. Free from bulkiness and thoroughly sober, she ventures into Hengshi alone with two hundred yuan, biting the bullet to rise from the bottom as an extra. While starring as Princess Pingzhao in "The Yunqing Chronicles", she boldly rewrites her scenes, subduing the furious director with her deeply layered performance. The drama's viewership breaks 52, her ascension scene goes viral across the internet, and her counter-wind comeback startles everyone. Facing her sudden explosion of fame, Shang Yechu maintains a calm expression, deeply aware that this is merely the beginning of her counterattack and revenge.
