Shi Qingxuan and Sharky haven't threaded yet, but the idea of the two of them both late-night skinny dipping in the hot tubs is really amusing to me because Shi Qingxuan wouldn't be the least bit embarrassed to do it with and would treat it like a chill casual hangout. He also likes hanging around Hurikane and wandering around Infinite Tommy Bahama in hopes of finding something that looks good.

Handwaved casual acquaintances maybe? Shi Qingxuan is easygoing and friendly, so he'd definitely chat.
