This.
If this was 1/2, and V1 was a 1/2 player, then ya, he probably jizzed his pants with a set and I can hopefully find a fold. But I'd be inclined to give a 5/10 reg credit for a few more brain cells than "I HAVE A SET! ALL IN!"
As played, I cannot fathom how he shows up with AA here. But hey, I'll take it.
Edit: "I misplayed this hand" is LOL. He told you exactly where you're at (ahead) and how you should play (call). WP.
