After the zombie virus broke out, the survivor base where I was located was brutally controlled by the overlord He Long. The female protagonist's parents favored boys over girls and, in exchange for two steamed buns for their young son, personally handed her over to He Long in exchange for food. I felt heartbroken and desperate, recalling that the biscuits I had risked my life to find were all given to my younger brother, while I was abandoned like this by my biological parents, with only my grandma having ever loved her.
