Manga Readers really need to keep a lid on things until things happen. I've seen ntohing but:
"You lot think it's boring- WAIT TILL [Moment something awesome happens] GETS HERE. STICK AROUND!"
Like, yes, we're not gonna drop it, or something. Stop trying to express how you know what's gonna happen in one way or another. Just watch everyone's reaction and be happy with that. You don't need to tell everyone how you know what's gonna happen.
