That's not setup, that's still foreshadowing. The Grimm Fish didn't make their appearance until that very post, and on first event you auto-hit?
There's three stages.
Foreshadowing, setup, and then the event/appearance.
It's called proper buildup. Don't tell me in a game you find it enjoyable when you get hit during a cutscene, because that's about what you did.
It takes a lot of effort and intricate setup to do what you did, but for now in general... Do not auto-hit. There are people who would react way more badly to it than I am.
