fat lad at the back story

Qiao Mei transmigrated into a novel as a supporting character with the same name as her who lacked presence. This supporting character was a country bumpkin who couldn’t get married due to her obesity. According to the original script, this country girl Qiao Mei was a fatty spoiled by her grandfather. However, their relatives were all vicious and cruel people. Her grandfather had poor health, so once he died, the relatives would divide and swallow up his assets. Hence, her grandfather’s greatest wish was to marry Qiao Mei off. For this, even sacrificed and betrayed his good friend’s grandson, Xia Zhe. Grandpa got Xia Zhe drunk and had Qiao Mei forcibly take the strong and handsome Xia Zhe with her body which weighed more than two hundred pounds. Then, grandpa would catch them the next day and force Xia Zhe to marry Qiao Mei. However, that eventually caused the start of Qiao Mei’s unfortunate life.
