Miss Liuying, I'm really not a bad guy

After traveling to the Starry Sky Railway World, he obtained a Starry Sky Train and the ability to travel through the world. He accidentally picked up a beautiful girl named "Firefly" and after this beautiful girl ate up all his savings for two and a half years, Wen Sheng decisively decided that he wanted to make money! Make money!
"Look at the rootless tree branching out, look at the boundless water rippling... Drive the train that belongs only to you, and create that..."
Wen Sheng: "What? Train! Transporting goods! Making money!"
"..."
Liuying: "I'm sorry... our conductor, he... he's not in his right mind."
The little boy with white hair and blue eyes was reflected in the purple-gold pupils. The rememberer, whose words were interrupted, was stunned for a moment, and then smiled.
"It's okay. Come to my room tonight. I'm quite knowledgeable about memory treatments~"
Liuying: "? I always feel like something is weird."
Wen Sheng: "Pull the goods! Make money! Pull the goods! Make money!"
Liuying: "Pulling goods... making money? But you are not losing..."
Wen Sheng: "I'm not a downtrodden dog!"
