KAT-TUN's Koki Tanaka 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 (Chiaki Kuriyama) 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 (Takashi Tsukamoto) and the eighth-year student Seishi Momoyama (Ryuji Akiyama).
