Shinsuke Kuwano, a successful architect at 40, enjoys living by himself. He doesn't like people but somehow is able to design wonderful houses for them.
He has a routine of making himself a delicious dinner and then relaxing to classical music in his easy chair while pretending he is the conductor. One night, he plays the music loud enough to make his next-door neighbor, Michiru Tamara, knock on his door to complain.
