Star Railway: The story of Kaffa being born with two babies at the start shocks her.

[Casual gameplay + multiple characters on board + storyline changes + original content in the mid-to-late game]
When Zhou Xingxing opened his eyes, he found himself unexpectedly transported into the body of Xing Qiong Tie Daoqiong, with a hazy Xing lying beside him.
Kaffa was staring blankly at the two who had just woken up.
"Let's call you Star and Sky."
"Da Ga, oral wah lu!"
Seeing that his mother pointed to him and said "Qiong," Zhou Xingxing immediately took Xing's name.
Since she's a younger sister, it's natural to call her Qiongmei.
So, accompanied by Qiong Mei, Zhou Xingxing, who already knew the script, and the Starry Sky Train group embarked on a journey that seemed to be quite different from the original script.
