"Lots of blind people in the world," Jungkook murmurs, glancing around with a small smile, trying to see if anyone is staring in their direction. It seems, for the most part, that everyone's involved in their own affairs, many of them wrangling children, others clearly glancing around in the way that tourists do. There's no obvious lingering glares, and it helps to set Jungkook more at ease, even if not enough yet to kiss Yoongi out in the open so close to a family-friendly attraction.

Just enough for him to wrap his arm tightly around Yoongi's own, keeping in step with him as they meander towards the aquarium's entrance.

Stumbling a little when Yoongi ventures to his next thought.

"Ah?" Jungkook stammers, face flooding over with color. A safeword — yes. Of course. It's probably something that he should have thought about before now, if Jungkook's honest, with how many restrictions in the bedroom the both of them have already played around with. Even if Jungkook's never seen the need before, if they plan on being discreet, if they plan on roleplaying, all of these are situations that demand a safety net to catch them both. "...have you been thinking about — do you have any suggestions?"
