As a dog, he has always known that this is an abnormal world. The alien species here wear human skin and spread all over the world disguised as humans. They feed on human flesh and blood and formulate the ultimate plan to exterminate mankind.
But none of that has anything to do with it.
It's just a dog, a weak, pitiful, smiling Samoyed.
[1V1, the male protagonist has a slight heartthrob attribute, everyone is a dog walker, everyone loves Samoyed, this makes sense^_^]
Purpose: Rebirth in desperate situation
