Link chose Malon.
Sorry, Zelink-fans, but I don't ship that coupling; I have a fic that states all my theories as to how Link and Zelda could be long-lost twins.
Plus, Malon lives a life just right for Link: it has plenty of hard work to it, yet he can enjoy himself as he tends to horses and cows and cuccos, and yet it is easy enough for him after all the world-saving that he's done.
Why would Link get together with Zelda and become King? Seems like Link would want to settle down and have a much easier life than castle-life, he's too much of the rugged-out-doorsy-type.
Plus Malon is sweet, brave (she set the original record for the corral race, remember?), beautiful, kind, selfless (she stayed behind at the ranch when Ingo took over so she could make certain Ingo wouldn't mistreat the horses), and she is the one who supplied him with Epona, AND she wasn't the one who sent him on a fool's mission!
Remember how Zelda sent Link to find all the stones so they could get the Triforce before Ganon and defeat him? If Zelda HADN'T sent Link on that mission, Ganondorf never would have gotten into the Sacred Realm and none of the tragic events would've happened to Hyrule.
Zelda's a fool and doesn't deserve Link. Malon does, she hasn't caused him as much grief as Zelda has - the only grief she's caused him is calling him "Fairy Boy", but y'know, Link was a Fairy Boy . . . he was a boy with a fairy, so yeah . . . plus she only called him that when they were kids, she didn't call him that when they were adults.
Plus Malon can sing and she and Link make a much more original and cuter coupling than the cliche of the handsome knight saving the helpless princess.
Well, that's my reasoning for the Malink pairing. Hope those of you who wanted Zelink aren't too disappointed. ;)
Well, good-bye:)
