Aiken wa Tsugai ni Naritai

Yuma, a handsome guy with a good income and an amiable personality, who is consistently dumped by his girlfriend with the question: "Who is more important to you, me or your dog?" Yuma values his dog Ryu more than anyone else. One day, when he was drunk, he made a promise to marry Ryu, and suddenly Ryu disappears. In his place appears a naked man with a collar around his neck. When Yuma seeks help from Ryu, the naked man inexplicably responds. Could it be that this man...? A love and sexy battle between a former dog who wants to be on top and his dog-loving owner.
