Jake ma boi, you need to get your shit together. Get it all together, and put it in a backpack - all your shit, so it’s together. And if you gotta take it somewhere, take it somewhere, you know, take it to the shit store and sell it, or put it in a shit museum, I don’t care what you do, you just gotta get it together. GET YOUR SHIT TOGETHER
I have a theory that someone found that cassette tape, then wrote all END all over it to distract and confuse the other players. The only one smart enough to do that (besides Doha) would be twink boi (the one who's always hanging around with dad joke guy). I have a feeling he's the mysterious 3rd player. These are only theories at this point, but I love a murder mystery and this manhwa is great!
GO GET YOUR MAN YOO-NIM!
