I speak and read Korean fluently too, and I never got the sense that Yuna HATES competition; she just disliked the pressure and the astounding media presence / attention that she got for every little thing she did on and off the ice. Such as...

Nobody's expected to love every aspect of something. But that doesn't mean that person intensely dislikes that something. I can still love something w/o not loving everything about it. I don't love everything about my job, but I still love my job overall. I don't love everything about motherhood, but I still love being a mom, and I adore my baby boy.
So Yuna can dislike the pressure & media attention, but she can still enjoy competition and competitive skating. She's said in her memoir and elsewhere that she loves performing before a big crowd, and skating well so that she can move the audience. She also indicated that she is a very competitive person.
