That fucking fishfuck
What the fuck is he trying to do? Like, seriously. Is his explanation actually directed to us readers? Eeeeerrrggghhh, if so, why not just have Professor Kitou internally monologuing about it instead. Reading any speech bubble coming from that fishfuck makes me nauseous.
I bet that fishfuck was pressuring Shingo because of pettiness or something (heck, I'm suspecting that the fishfuck is actually fluent in English). The kid is already really close to having a massive breakdown, kinda feels like to me that he doesn't really mean it whenever he wishes that Kunitachi's surgery would fail, meaning his dad's failed surgery would be the biggest trigger for his breakdown. I bet that fishfuck will just taunt Shingo even more once Kunitachi fails, worsening his breakdown.
