Mouse Turned Dog

Iwaizumi Umeji, little sister to the Ace of Aoba Johsai, has decided to finally get into the dating ring when a certain blonde saves her from a bad situation. Never one for cliche love stories, Umeji has decided to play a small game of Cat-and-Mouse and she plans to be the dog in mouse clothing. Deciding to play mouse is a lot harder for her than she thought, never being one for fawning over boys and making cookies. Ume might just have bitten off more than she can chew when her cat turns out to be a Dog himself.
Kyotani Kentaro was raised to never let a girl get hurt, so when he sees a girl in trouble he didn't hesitate to step in. But now that his foot in the game, he starts seeing how this girl is nothing like any other he's met, even if she's trying so hard to act like she is. When the game turns into reality, he can't help but want to be with her...even if she's more of a dog than a mouse, which is fine with him he's always been a dog person.
Now the real question, who is training who? Will Umeji shed her mousey appearance to let her feral side show or will Kentaro submit to the female that makes him feel like a puppy? Neither is willing to bend, but maybe with some help from the Great King and his knights, they'll see that it's okay to go a little wild when love is involved.
