@Leimama Actually I'm getting a feeling that Juhyeok wasn't really that passionate with his Judo career, like it was just a mean so he could protect Su Ah when he manifested as an omega, but because the role got reversed I think he used the Judo to prove himself against the omega-alpha system. And also, in chapter 15 didn't Juhyeok said something like "If only I didn't become an omega, mom would've...."—I think there's also an internal criticism within his family, remember in early chapters when Juhyeok’s aunt said that his grandparents didn't attend his omega manifestation party but she attended, meaning the story's been foreshadowing it. So I think that critism made Juhyeok self-loathed, because how can he love his self when even his own family can't accept him? And the worst yet heartbreaking thing is, he's projecting all that self-hatred and insecurities directly at Su Ah.
So I'm guessing that he's using the Judo to prove himself against the system that expects the omegas to be weak and can't survive without alphas, that's why he kept putting himself in that alpha-dominated space and repeatedly saying that he hated being talked about him being an omega.
