Pei Fei of the End of the World

In 2020, zombies are rampant and the world is in turmoil. Pei Fei, a 21-year-old female man, takes her 5-year-old younger brother Pei Lei on a journey of survival in the apocalypse. Later, when she meets Long Ya, Pei Fei goes from hostility to secret love, from secret love to clear love, and from a tomboy to a soft girl.
