Bitch I'm up

I need your help finding this horror manga basically all these people get kidnapped and they're all really bad people and did something bad in the real world and when they wake up they're all in this weird place that punishes bad people basically and from what I can remember the main character is a guy and I'm pretty sure he can't remember what he did wrong but I could be wrong since I did read this a long time ago there's also higher ups who are supervising this it's almost like a game because there's other people from the outside world watching all this happen as entertainment and they wear masks like really weird masks so you can't see their face and it was just very unsettling especially the art style does this ring a bell to anybody I also remember a character with pink hair that was like a higher up or something in the later chapters and it was a girl

Can you guys help me out please i’m trying to find a story I read, but I didn’t bookmark. It only had one chapter and it was a BL. Basically the mc has dark black hair and looks really tough, but it’s actually really shy and a scaredy-cat but he pretends to be tough because he doesn’t want people looking down on him and he works in like this customer service thing and then the.ML HAS BLONDE HAIR AND HE ALSO WORKS AT THE SAME PLACE AS THE MC DOES AND HE APPEARS REALLY NICE AND FRIENDLY, BUT HE’S ACTUALLY TWO-FACED AND SPREADS BAD RUMORS ABOUT THE MC FOR SOME REASON AFTER GAINING HIS TRUST ummmm I don’t know why all the words turned really big but I’m too lazy to type all that out again well to be fair I was using Siri, but please just ignore that
