Is It Really Okay to Transmigrate from a Zombie World to Girls' Frontline?

I just got into Girls' Frontline recently, and after reading so many great stories by the veteran authors, I wanted to try writing one myself. (Mainly because I can't afford to read anymore.)

Serious introduction:

Yi Wei was an ordinary student in the 21st century. After his parents passed away, he started traveling to clear his head. But he unexpectedly transmigrated to a world... full of zombies. Decades of survival and learning did not strip away his humanity. Just when he thought he would spend the rest of his life surviving there, he transmigrated once again... to Girls' Frontline.
