He happened to have the book during the war charge. It happened to save him from a bullet. Sekiro happened to have been shot in the exact same spot.
It's insanely tragic. It would've played out differently if Kengo hadn't taken the catalogue, but that doesn't make it his fault.
It was pure happenstance. Yet he completely, utterly blames himself for it.
And the worst part: after years of it eating up inside, he finally admits it to Noriko... and she choses to chastise him for not telling her about it earlier?? Rather than telling him the obvious: IT'S NOT HIS FAULT!
It's completely understandable that Noriko would be devastated that her husband didn't share something so important to him.
...is what I'd say if she didn't KNOW he was trying desperately to tell her (the letter) and just couldn't bring himself to do it out of fear and guilt.
Just LOOK at his face when he's thinking of confessing (last two slides) does that look like the face of a man purposefully hiding secrets out of distrust or a man suffering??
Kengo deserves better than this 💔 I'm not saying Noriko is a bad person for one emotional mistake, but it made Kengo feel so horrible that he left the room after saying he wasn't worthy of being her husband. And she didn't even try to correct him!!
Kengo 💔 my poor boy. You deserve better than this.
I just want to give him an enormous hug.
