Teaching at a swimming pool frequented by ultra sexy women ought to be the ultimate dream job, but for glorified litter-picker Yoo Myungjin, it isn't quite what he'd expected. Everything begins to change, however, when he gets his first taste of hands-on teaching with the oh-so-stunning Yura, and not long after that he's approached with a deal that's too tantalizing to refuse. Is this finally his chance to get a taste of real teaching, and all the perks that come with it? A game of love and lust is officially underway, but just what will go on beneath the waves?
