Okay, I read the book so let me explain the smoking part because it is a bit confusing here. Youngwon vaguely remembers hearing from someone that the sensation of smoking is somewhat similar to the aftertaste of an affair. He wonders if this stranger (Hohyun) has a lover and if it's a woman or a man. He concludes that his encounters likely lean towards women, given how he carried himself and his conformity to societal norms. He indulges in sexual fantasies about him. He wonders what kind of facial expression he makes when he reaches orgasm, and whether he smokes after sex while naked and unguarded.
Who translated it? I read it under paywall at wordexcrept site, they're the ones who had license at the time. Now they have 3 volumes up. The TL was kinda bad as in they used a ton of fancy words and it felt unnatural like TL by chatGPT. And they have censored all the intimate scenes out.
Is the amazon version different?
At the beginning, Bada describes the game as your typical slasher game, where a group of college students drive to a house in the middle of the woods for an overnight getaway and are murdered there. In a later iteration, Jaeseob says that the reason they are there is to do volunteer work. I can't help but find this bit a little odd tbh. I also wonder what kind of volunteer work they were supposed to do and if it has anything to do with the plot.
