I mean, Omori's stare just says it all.

Wait, is this a route I haven’t played yet? Never seen this picture before

I found the picture on the game's Website.
If you scroll down there's a mini Whitespace. Go on the door and if you reach the slots part, tap/click on the machine when you lose, that photo will appear

Omori: Kel, you dumb bitch-

XD
