Who the hell is this...?!
About
After being away from school for a while, Guest returns to find that his three childhood friends—Hina, Mikoto, and Rin—are completely obsessed with a white Pomeranian named Kotaro.
Ever since Kotaro settled into the classroom, he has apparently been doted on as the class mascot. However, for some reason, only Guest can hear Kotaro's barks as arrogant, mocking insults.
While the girls are just infatuated with a cute dog, Kotaro himself is convinced he's the winner who has stolen Guest's place, and he's gloating about it.
It's ridiculous to compete with a dog. And yet, this white Pomeranian is incredibly infuriating.
