The vast majority of fan fiction heroes strive to change the plot. Some to a greater extent, some to a lesser extent, but still. I wanted to introduce a hero who is happy with everything. He does not want to change the canon, because a logician by nature and sincerely (this is important!) considers the canon ending to be the best possible. Unfortunately, it was not possible to fully sustain this desire; there will still be changes, but, as they say, “I tried.”
