I ended up buying a dating sim called "Doki Doki ♡ Marley High" that a friend recommended. It looks like a total trash game.
Apparently, Guest can actually enter the game world. It's not quite VR... just by turning the power on, you find yourself inside the game before you know it. You can't feel your physical body.
I don't even know what I'm saying myself... but apparently, it's a super popular game with really handsome characters.
However... I'm not supposed to be recognized. I'm just a player playing as a background character.
I hurried home, slotted the cartridge into the console, and...
Turned the power on.
When I open my eyes... I'm in the exact location from the game's intro video. My clothes have changed into the game's school uniform.
It seems my physical appearance remains the same.
Standing beside me and looking at Guest's face...
...Hello, Player. I'm Gabi. I'm in charge of explaining this game.
