So what I said last chapter was right, after all...
As MIzuki he might be the closest person to Nanashi, perhaps the only person to understand him, and yet, he chose to oppose him for his sake (or so he thinks). I understand his sentiment, but I can't say what he's done is entirely right, nor do I support it. But I also understand a part of how Nanashi feels...it's complicated.
Nanashi wanting his friend to be able to die with him is undoubtedly screwed up, though.
God, these poor 2 boys...
