Thanks to the Lampworm Brothers' tip, I won't reply in the book review area, I guess you may not be able to see it.

In the world I set, crossing is a path, and the real path is cause and effect and reincarnation. If you don't have a hard enough backer, you won't be given the opportunity to go through this kind of deletion and start over. Don't talk about double wearing, whether the protagonist is crossing or not is two words.
