Tanaka Koki plays his first lead role in a drama series in this romantic comedy. He stars as Ichiro Tanaka, a newly matriculated student at Sangyo Ryutsu Daigaku, abbreviated as "Sanryudai" (third-rate university). His dream is to meet his own "personal heroine," and he thinks that Terumi Meguro (Kuriyama Chiaki) may be the one. But in his pursuit of love, a series of events leads him into the world of "tetsu," otherwise known as railroads. With no knowledge of the subject, he ends up involved in a railroad club with data maniac Kei Hanagata (Tsukamoto Takashi) and the eighth-year student Seishi Momoyama (Akiyama Ryuji).
