the “agreement theory” is from anon called wink and the three of them believed it.I also noticed that they paint Harry as innocent and victim,they don’t want to accept the fact that nobody force Harry to be with Meghan its purely Harry’s choice and decisions.

Uh, not quite. The “agreement” theory originated back when H&M were dating. It was an explanation as to why there was so much pr shit going on with Megs. 

I’ve written about “Wink” before.

Now, the “agreement” theory as it regards to the wedding/engagement, you can choose what you want to believe about it. Either the Conspiracy Trio didn’t want believe the engagement was real and just stuck with the previous theory, or “Wink” encouraged them to believe it since s/he is a longtime anon/contributor.

Up to you.
