After two years of preparation, Ichiro Tanaka finally enters a university disdained as a third-class one. Out of his ardent desire to become popular with girls, he by chance steps into the world of the railroad “otaku” (commonly called “tetsu”), getting deeply involved in the fascinating railroad world. This drama portrays Ichiro who, together with those lonely “tetsu” guys he meets there who “want to be popular so badly but are not,” develops love and friendship and grows mature as a person.
