Pools aren't really my thing

Seonghwa and his brothers have been mermaids for a couple years now and have learned to live with and love their powers. They always had each other, but now its the summer before Seonghwa's first year of college. He is both excited and nervous as it will be different and he will have to deal with keeping his secret hidden all on his own. However there is something he didn't consider before hand, having a massive crush on the beautiful red haired man he'd met that summer and would be going to school with the comping semester for example. And when you're invited to a party by your crush what else are you to do but go? Too bad he hadn't told him about his aversion to water.
