Plot
Shinsuke Kuwano (Abe Hiroshi), a successful architect at 40, enjoys living by himself. He doesn't like people but somehow is able to design wonderful houses for them.

Kuwano is incredibly socially awkward, to the point of being rude, however, he often means well, and is generally at a loss as to why he annoys people around him (which he does consistently). While he is a loner, he has regular contact with his family, his mother in particular is trying to get him married. His day to day contact with his long suffering employee Eiji (Tsukamoto Takashi) and business manager Maya Sawazaki (Takashima Reiko) is troublesome, they see him as awkward, but as he is the core talent of the business, they put up with his antisocial ways. This generally involves them placating clients and trying to cover for the fact he sometimes insults them without even realising it.

He has a routine of making himself a delicious dinner and then relaxing to classical music in his easy chair (he likes to pretend that he is the conductor). One night, he plays the music loud enough to make his next door neighbor, Michiru Tamura (Kuninaka Ryoko) knock on his door to complain. When Kuwano answers the door, he suffers terrible stomach pain and collapses to the floor. Lucky for him, his neighbor Michiru is nice enough to accompany him to the hospital, where he is treated by Dr. Natsumi Hayasaka (Natsukawa Yui). He is really rude to Natsumi, but she is still determined to treat him.

Afterwards, Michiru and Natsumi become part of Kuwano's life. They make friends with Kuwano's colleagues Eiji and Maya. While becoming friends they all enjoy talking about how strange and eccentric Kuwano is. As time goes by, they all see something in Kuwano, while Kuwano himself changes his habits and starts to slowly appreciate the people around him.

Additionally Kuwano has a rival architect, Kaneda, whom he despises, though he seems interested in his extravagant lifestyle. Kaneda, only seem to use the cover of an architect as a cover to get girls and impress people. This intrigues Kuwano, who constantly checks his website to see if Kaneda actually builds anything. Kaneda is an architect like Kuwano, and around the exact age, they are polar opposites.
