"I want you as my bride!"

One rainy day, Akitaka, a vet, had helped rescue an injured wolf. Later, an unknown young man named Rio and his attendant, Sakaki, visited him saying that they want to give him thanks for his help back then.

When Akitaka refused their thanks, claiming that they had the wrong person, that's when the very ears and tail that Akitaka had seen on that rainy day popped out from Rio's body. Apparently, Rio is a royalty who's next in line to the throne's succession and he has come to take Akitaka as his princess...!?

While it's unclear if he fully understood the whole thing, Akitaka, in his irritation, kissed Rio who then ran away from the shock of it. However, Rio returned the next day undiscouraged and began to show his affection.

This is the sweet and passionate romance of a pure and dumb wolf prince who's always giving his all in showing his love and the unfriendly and misanthrope vet whose heart eventually opens up from being healed by it.
