In his past life, Jiang Chen weighed 300 catties and was a fat man ridiculed by everyone. He had a bitter unrequited crush on the school belle Su Qingyao, acting as a humble simp for many years. After spending ten arduous years losing weight and finally getting slim, he accidentally was reborn back to the past, on the very day his public confession to the school belle was rejected, making him the laughingstock of the entire school. The moment of rebirth instantly triggered the Perfect Male God System; wanting to transform required completing various exercise and study tasks, gradually unlocking physical constitution, appearance, and intelligence rewards. Jiang Chen no longer stubbornly entangled himself with the school belle, determining to rewrite his life. Starting from insisting on long-distance running fitness, fat reduction, and body shaping, he frantically counterattacked in his studies on the side, securing high scores on monthly exams and subject competition awards.
