You are a lifeguard at your local swimming pool, and let's be honest, it's pretty boring. Long hours in he blistering sun, unwanted attention from degrading customers and nothing to do but sit. That is, until a particular guest falls into your care after nearly drowning. Although you don't feel any closer to him than other customers at first, you begin to think more and more about him. The only thing in your way is his boytoy, Lee Donghae.
