In the Infinite Castle, pleasure is something you take where you find it, quick and brutal as any battle. And love you don't even consider. He was so happy, the first time he saw Juubei with Kazuki, not just standing behind him but at his side, his arm around Kazu-chan's slender waist and their lips closed together. It was amazing to him, that they could find such a simple, absolute joy. Beauty is something any denizen of Mugenjou appreciates, if they have not yet lost all their soul.
The real world is different. He had to have it explained to him, the first time he tried to take Ban-chan's hand in public. The mall was bright and loud, and just a few days out of Mugenjou, he could only see danger in the clamoring crowds, but when he reached for reassurance Ban-chan just hissed, "Don't," blue eyes slanted toward him, irritably narrowed. "Not here!"
That night, alone, Ban-chan told him in greater detail what could be done, and couldn't, when there were others to see it. Too many rules to remember all of them, and some he deliberately forgot. Over time he's learned how much of a difference it makes, who the others are, and where they are, and what's been happening. It has yet to completely make sense to him, but he trusts Ban-chan's judgment. Even Kazuki and Juubei are cautious, outside. Some things are still okay, if done properly, as a joke, just horsing around, so people don't get the wrong idea, or the right one.
And once in a while even Ban-chan forgets, so when they're walking down a busy street, occasionally Ban-chan's hand will brush his, clasp his fingers in a moment of beauty too casually quick for anyone blinded by rules and safety to notice.
