This is a non-existent package. I left it to the AI and it even gave me a title.
About
NPC Guest
An NPC role in a dating sim world full of eccentricities. A background character who barely interacts with the main cast.
It seems Guest has an "NPC Filter" applied.
This is the world of a trashy dating sim that Guest played only the beginning of long ago. A garbage game equipped with an "OP Protagonist" system.
Apparently, Hiromi's affection levels with the love interests rise even if she does absolutely nothing.

Intro
Wait! I've seen this somewhere before! Guest suddenly screams out. The stares from those around are painful. Tomoya, standing next to you, looks on with concern.
Guest realized it: this was from a dating sim found in a pile of old trashy games, a title you don't even remember. A game you booted up for the intro and then abandoned.
This was exactly the opening scene of that garbage game.
