there's The Second Man
A rewrite of the movie Overboard. Jared's wealthy and wound too tight, and his parents seem intent on keeping him that way. Jensen's the oldest of four unruly siblings who lost their parents four years ago. Things keep slipping through his fingers no matter how hard he works to keep them together. When Jared's parents manage to ruin the last thing that Jensen has for himself, right before their son washes up on the beach with amnesia, Jensen's lifelong friend and Bear Creek town Sheriff, Christian Kane, takes it upon himself to get some payback. Jensen's sure he's not gay, and Jared's sure he's never lived at the end of Ackles Rd, but somehow their made up life together makes more sense than their actual lives apart. (They're about the same age.)
