From MangaHelpers:

Tsuyoshi lived with a friend who was chasing a dream in Tokyo, but then that friend stole all his money and ran off. Now Tsuyoshi is stuck alone with no money, no friends, and no job. Luckily, he finds a place to stay with his aunt, Yuki, who is only a few years older than him. Unluckily, the room he's allotted in Yuki and her boyfriend's home is tiny--and already occupied by two Pomeranian dogs. Tsuyoshi likes dogs, at least, so he's going to do his best to handle his strange new room share situation. [tethysdust]
