A world where pets like dogs and cats naturally exist in human form. Faithful dog Hachi loves his master wholeheartedly and so he gets very jealous. Hachi's owner, Kentarou, is a bit of a push-over and overwhelmed by Hachi's frankness and desire to monopolize him every day.
Then one day, Kentarou is struck with fever and stays home from university. The one who comes by to his room to check up on him, is a girl who takes the same seminar. Feeling the situation is getting quite intimate, Hachi's jealousy and impatience explodes-- (Translated by ZHAO)
An everyday guy who lives on his own with one pet in an apartment in a metropolitan area. He's vaguely thinking about wanting to have a girlfriend, but with jealous Hachi's interfering, and his own primarily lazy disposition, he finds himself not undertaking any actions in particular. He picked up abandoned dog Hachi, wanting to raise the dog as devoted to himself as the famous faithful dog Hachiko, and so, gave him the name "Hachi". Kentarou is a push-over, but it's not like he's timid. It seems like he treats Hachi rudely, but in fact he thinks Hachi is irresistibly cute.
"If I didn't like you... would I ever have made you my pet?!? You... stupid dog!!"

A cheerful dog who loves his owner Kentarou more than anything. He was picked up by Kentarou after being abandoned right after he was born. He loves Kentarou so much that he acknowledges all the girls who come close as enemies and intimidates them. Crossing the borders of race, Hachi wishes to become Kentarou's mate. Brimming with curiosity, he wants to know anything about things he's interested in. His information source is a dog from a house Hachi passes on his walking route, who goes by the nickname "Tarou-san from Sanchome".
