Im still on board that Guwon though MC actually remembered properly not realizing that Teach actually is still in denial and inserted Guwon into his own place in his memories. Remember we are still in MCs perspective and he is a bad narrator so the "true memories" are still fake but now he can visualize it better now that he in in the place where it happened. This helps make what Guwon say make more sense when he confirmed that he didn't lie
I love the unreliable narrator trope. I really do hope that's the case and everything starts making sense at some point cause Guwon seems like such an interesting character (▰˘◡˘▰)
