The story begins with Izumi Hayato running to be student body president. But when a beautiful girl swings in promising the liberalization of love while flinging condoms into the audience, he ends up losing to her and becoming the vice president. At the student council meeting, the newly-elected president invites herself over to Izumi's house, where she promptly announces she is to become Izumi's wife thanks to an agreement that their parents had made, a drunken promise decades ago that their children would one day become husband and wife. Naturally Hayato is against this, but Ui has the complete opposite reaction, and even wants to live with him! Will the upset Hayato and the overenthusiastic Ui be able to manage their school and marital life while keeping it a secret from the other students? Or will the two never come to understand each other's feelings?

The story revolves around Nekoyama Suzu, a timid, shy tsundere girl loves dogs, and Inugami Yachiyo, a super masochistic, air-headed, friendly girl who loves cats. One day, after a fateful meeting, the two find themselves attracted to each other. In response to Inugami's instinctive approaches, Nekoyama is always bashful. Their friend Aki has to work hard to make jabs at some of the situations of the two, and also to stop Inugami from going berserk.
