"Algebra works," Jungkook muses, his voice a little more distant now for the attention that he's paying to their surroundings, strategically letting go of Yoongi's hand before they step into the bathroom. It's busy, as perhaps is to be expected for the weekend, but it's also large — two full rows of stalls beyond the urinals, with most people weaving in and out of the closer row.

Jungkook briefly glances over his shoulder, meeting Yoongi's gaze for a second and biting down on his lower lip, chewing it as he heads for the second row of stalls. A couple of fathers are chasing around after their young sons, and it makes for enough distraction that Jungkook doesn't think anyone will notice when he neglects to lock the door behind him, heading into one of the last stalls down the line.

Thankfully, everything seems fairly clean.
