Cheng Sheng, whose parents died and was raising his younger sister by himself, was lucky enough to get into a high school because of his extraordinary performance in the high school entrance examination. He met Yan Jiayi, who grew up in a privileged family, was personable, had top grades, and had a dog-like appearance, and became his right-hand man. This "student scumbag" Cheng Sheng gradually gets closer to the "study god" Yan Jiayi, integrates into Yan Jiayi's family, and gradually becomes an indispensable part of Yan Jiayi's side. The two people who had no intersection at first accidentally bumped into each other's future and slowly moved forward. Intention: Study hard and make progress every day
