The story begins with a top student in pharmacy school who harbors the dream of becoming an "angel in white". In seven years, he has transformed from a newbie in the industry to a "senior representative" who is well versed in gray rules, but he has endured endless soul torture between the bonuses on his bank card and the trembling payment slips outside the ward. He handed the thick notes recording his seven years of struggle and ups and downs to his apprentice Xiaolin, leaving only one sentence: "You see and judge for yourself."
