Baekhyun's purple buttplug

So the plot goes that the mc would be working in a firm and would be hiding the fact that he's gay as fuck with a ring and also when hed be doing military service there would a dude who's our ml who'd keep on appearing in his wet dreams so the mc would be ignoring the poor dude and making him do hard stuff purposely. And now it turns out that the ml is now his companys head or shit like that pls tell me if y'all know it the title is something about lies or misunderstanding I don't remember

So there's this yuri/gl where they are both office workers and they hate like really HATE each other and they beat each ither up it's super violent and they have sex so it's basically office hate violent sex gl
