i started living under the same roof with yukino, my girlfriend and her best friend minami, who were former colleagues at the company, but my girlfriend, who has lost interest in me, a freeter who can't get ahead in life, starts looking at other men. i try to switch to minami, who i secretly like, but she says "if you really like me... please endure for a month until yukino goes to training" in order to prove my feelings, we both live a life of abstinence... the moment she becomes 'absent', my libido explodes! a forbidden love-hate drama where we devour each other like beasts, forgetting ourselves.
