Maybe you'll like Act Out!
Ibara Nayuki is a figure skater who performs around the globe, but audiences grow fed up with his passionless performances, and his coach doesn't know what to do with him. Just then, who should appear before him but Vasily, a ballet dancer once hailed as a child prodigy? "Not knowing why you're there in the rink is as good as not knowing who you really are!"

Lately, I’ve been really into Medalist. I’m looking for manga suggestions that play into the genius aspect (MC is a genius at what they do, and are unmatched), and the relationship between Jun and Tsubasa (the foil, and tense relationship between them, and the slight obsession element between them). I’m fine with themes outside of sports, and the recommendations don’t necessarily need to include both elements that I’m looking for (genius mc + rivalry/ relationship), and can include one or the other.
