In his previous life, the protagonist was an ordinary employee at a railway operations depot. He worked hard for decades, but because he didn’t understand the rules and missed his chances, he retired in a low-level position. He watched former colleagues climb the ranks while the railway industry rapidly advanced, and was left full of regret. After an accident leaves him reborn in 2005, at the point when he has just joined the depot as a frontline passenger service worker, he draws on decades of railway experience from his previous life and his foresight into the industry’s future. Starting from the bottom, he carefully works his way up and makes a stunning comeback to become the head of the depot.
