Saw this earlier today and had to add the words.

This is the most upsetting thing I’ve seen

“Everyone is alone. Everyone is empty. People no longer have need of others. You can always find a spare for any replacement. Any relationship can be replaced. I had gotten bored of a world like that. But for some reason… the thought that someone other than you might kill me never occurred to me. Say, what do you think Kougami? After this, will you be able to find a replacement for me?” - Shogo Makishima
