People are always used to thinking of a predetermined happy ending for a story, but they don't know that the protagonist is no longer so optimistic about the ending after experiencing so much.

Even if you fight hard and put in all your efforts, it is not as good as a sneeze from God. Deep fate and shallow fate are already destined.
