This game's visual novel side is pretty much just a facade that the game's creator used for bamboozle and fun-making effects.

Despite of this, the /r/DDLC subreddit is full of people exactly on the spectrum of people the game pokes fun at, and are quite attached to the VN side, probably more so than the horror side. Thus this image's message.

I think it's hard to poke fun of weeb culture because there's so much self-loathing already embedded in it, ironic and unironic.
