Don't worry, its not just you the fandom is really taken down.

Particularly the game has many endings and routes to go along all. Plus the main missions are already giving instructions, and also the version updates are already posted above if you want to go with a certain route such as if you hate or romance a particular character. Honestly the fandom guide does not give the full coverage of the game.
It just makes you do the likely (obvious romance route for the early scenario up to you beat Bradley. The game is way beyond over that and that's just the second boss.)
