Starry Sky Railway: The birth of two children shocked Kafka

[Casual + Multiple Characters + Plot Changes + Mid-to-late Originality]
When he opened his eyes, Zhou Xingxing found that he had accidentally traveled into the body of Xingqiong Railway Dome, with a hazy Xing lying beside him.
Kafka was looking at the two people who had just woken up in confusion.
"Just call yourself Xing and Qiong."
"Da ga, ko wa lu!"
Seeing that Ka Ma pointed at himself and mentioned Qiong, Zhou Xingxing immediately grabbed Xing's name.
As for my younger sister, it’s better to call her Qiongmei.
So, Zhou Xingxing, who already knew the script, took his sister Qiong and the Starry Sky Train with him, embarked on a journey that seemed different from the original script.
