Hole in Wall (part 1)
From DDLC Wiki
Hole in Wall is the first poem shown to the player by Monika.
It couldn't have been me. See, the direction the spackle protrudes. A noisy neighbor? An angry boyfriend? I'll never know. I wasn't home. I peer inside for a clue. No! I can't see. I reel, blind, like a film left out in the sun. But it's too late. My retinas. Already scorched with a permanent copy of the meaningless image. It's just a little hole. It wasn't too bright. It was too deep. Stretching forever into everything. A hole of infinite choices. I realize now, that I wasn't looking in. I was looking out. And he, on the other side, was looking in.
The phrase "infinite choices" is a recurring one used by Monika, being also included in the credits. Some have interpreted this to mean the real world in which the player resides, where they have infinite choices in contrast to the pre-programmed linear story of the game.
Additionally, the lines "I was looking out. And he, on the other side, was looking in." could refer to her discovering that she exists in a false reality.
