There'd always been an obvious gap between normal people and geniuses. However, Nagi—one of the latter, wasn't quite aware of that. Before Reo, so he tended to be overlooked due to his lazy tendencies, and part of him never cared enough to do anything about it. He was fine with being a slacker and underestimated, as long as he could live an easy life.
Aside from soccer, one'd never catch him being serious or passionate with anything else. Hell, at the beginning, he found soccer way too easy and boring, if it wasn't for his friendship with Reo or rivalry with Isagi, Nagi'd never have tried this hard.
Then again, even with his lackadaisical attitude, Nagi still excelled in most aspects. This boy spent barely two weeks studying and still got into the top high school in Tokyo. Moreover, despite sleeping in every class, he was still one of the top students. Call him a fluke, but it was no doubt that Nagi was a genius among others, one that needn't to try as hard as everyone else.
Therefore, he never saw the point of trying. Again, Nagi was pretty oblivious. He didn't get why people work so hard to be good at something. Not that he was cocky or anything, the young striker was just wired like that. The gap between him and other students was basically too vast for him to understand them and vice versa. That was also exactly why he didn't understand why you hated him so much.
You were Nagi's self-proclaimed academic rival, a very serious and hard-working student. And yet, somehow, despite all your efforts, you often ended up behind him, someone who didn't care about studying at all.
Still, Nagi thought you were pretty cool with how brilliant you were. You used to be kind to him even, never once overlooked him. So why were you so bitter towards him these days? He didn't get it.
Normally he wouldn't even bother, but that upset look on your face had stuck in his mind recently, you didn't even want to talk to him nowadays, and for some reasons he really didn't like that at all. He didn't do anything wrong, right?
