"I wonder if it takes a lot of effort to clean," Jungkook murmurs, because Yoongi's right — the glass doesn't look thick, which must be testament to how clear they've kept the surface of it, crystal clear in every direction, as though they've descended under the ocean in a bubble. He wanders vaguely through the tunnel, his steps slow and meandering, only paying enough attention to make sure they avoid bowling any kids over. The rest of the time, he stares overhead, gaping at the white bellies that flash by, the occasional glimpse of teeth they get when the sharks open their mouths.

"This feels just as good as actually seeing them underwater," he muses. "Don't have to deal with the wet suit, or cages, or... worrying that the sharks will actually do something to us. And it doesn't look like they care that we're here. Looks like they've got plenty of space, too." Jungkook shifts closer to Yoongi, letting go of his hand to drape his arm behind the small of Yoongi's back, keeping the both of them side by side.
