Miss Firefly, I'm Really Not a Dog-eater

Having transmigrated to the Starry Sky Railway world, Wen Sheng acquired a Starry Sky Train and the ability to travel between worlds. He accidentally picked up a beautiful girl named "Firefly," and after she ate all his savings from two and a half years, Wen Sheng decisively decided he had to make money! Make money! "See the rootless tree branching out, see the boundless water rippling... Drive your own train, to create that..." Wen Sheng: "What? A train! Cargo! Make money!" "..." Firefly: "Sorry... our train conductor, he... he's a little mentally challenged." The white-haired, blue-eyed boy was reflected in his purple-gold pupils. The one whose words were interrupted paused slightly, then smiled. "It's alright, come to my room tonight. I'm quite knowledgeable about memory treatments~" Firefly: "? Something feels off." Wen Sheng: "Cargo! Make money! Cargo! Make money!" Firefly: "Cargo... make money? But you're just..." Wen Sheng: "I'm not a swindler!"
