You speak as though he showed you his hand though. This is the problem I'm having. You act like it is a fact that he had KQ, despite all the evidence to the contrary. Literally every decision he made in the entire hand, on every street, screams "definitely not KQ". The only thing suggesting it is his word after the fact. A poker player's word about what he had. And in a hand where you do very clearly had AK. In a conversation where even you yourself admit to lying to him about what you had.
You suggesting that we're all fools for sticking to our reads even after we've been "proven wrong" is what I find so hilarious in this hand, and it's why I keep giving you shit. There is no reason whatsoever that we should believe your friend. And we have every reason not to. If he showed you KQ, then that would be entirely different, and we'd be having a different conversation about how your player type reads ("he's a tight player") are in serious need of adjustment. But the word of a poker player about what they had after a hand (regardless of how nice they are or how honest you perceive them to be) means absolutely nothing. Poker players feel zero obligation to tell you the truth about what they had. Even the kindest and most gentle hearted players will lie straight to your face. I learned this lesson very early on in my career. Even old man coffee and sweet aunt Suzie will lie straight to your face. Even the best of friends as well. It's just part of the game.
