Looking at this and the "prequel" chapters: Dude puts his head into the mouth of the lion at every moment he can. Like, he put it once and got bitten by Shirosaki into being his bully; now he did it again and willingly entered the house of the crazy girl that proposed the plan to kill Shirosaki.
Like, I kinda hope he can get out of this situation somehow but I feel he would probably fall into a similar problem again without noticing
