You should probably stop reading Manga... this kind of shit is pretty much the trend.
It's either: Create a MC, give him/her a well defined objective, manga gets popular, ignore the objective and milk this shit for everything it got until everybody hates it.
Or: Create MC, give him/her an OK objective, manga isn't popular, axe this shit with a dumb, out of character ending.
And this applies to Shounen, Shoujo, Seinen, Josei...
Chinese Manhua are pretty much all the same story, with very few exceptions.
Go read Manhwa. The Korean authors are pretty great still. They usually adapt novels that are already finished and follow the story to the T with crazy good art.
Better enjoy it while it lasts.
