Spoof version:
On an earth that has experienced the apocalypse, Lin Bai, the only real human being known to us, can finally hold hands with his pet dog without any scruples and grow old together with him. But such immoral love is of course strongly opposed by a group of righteous people (really?). So between eating and being eaten, my imagination started like this~
Normal version:
Thanks to the high technology of the 21st century, Lin Bai escaped a human catastrophe and became one of the few humans to survive. But the world outside has been turned upside down. After a zombie craze, all species on earth have evolved a devouring gene. Genes evolved that could be taken in from other species by eating them. Lin Bai was lucky enough to wake up after this zombie disaster. But how can he live with a picked-up puppy who has no understanding of the current earth?
