It could be a translation issue. I heard some people saying there were issues with it for Ch20. It just seems odd to me that he would be betraying Yashiro. I haven't actually read 19 or 20 myself yet so maybe I shouldn't even comment lol but there is supposed to be a different translation of 20 coming out in the future
the transaltion for chapter 20 isn't the same people who did the other chapters. it's not a good translation. I'm going to wait for lustful cat's version of chapter 20
The cleaners said Misumi might know what's going on, but prefers to stand out of it. That might be the reason why Yashiro said it, but we have seen Misumi's POV too, so we know he is on Yashiro's side or it seemed so.
Guys, I don't get it. If Misumi-san is like a ''father'' and if he likes Yashiro what's with that ''This time around I'd never thought Misumi-san'd be the one doing it''? So was Misumi into all this betraying?
