(It's not systematic, it's not brainless, it doesn't have a harem, it's not a cool novel, there are twists and turns, there are foreshadowings, please be careful if you mind)
At first we just thought it was an adventure on the bus, until death appeared
When we died, we started to panic.
Then we arrived at a hospital. We thought it was just another reincarnation.
It wasn't until the mystery of the story was finally solved that we discovered the intricacies behind it.
(This is my first time writing a novel. It's a bit long and I'm slow to get into the topic. If some readers are anxious, you can start reading from the later chapters. Of course, you may miss some main content. There are also some things in the front that may seem strange to you, but trust me, when you read the back, I hope you can be more patient with emerging things. Maybe you will be surprised by the end of this book.)
