Kuon doesn't understand. He had willingly betrayed his own team just for his own benefits, resulting in them hating him and treating him like an outsider. He was no longer considered a part of Team Z. He had leaked their team formation and plan to Team W, just so he could be the top scorer.
He even got beat up by the Wanima Twins for apparently giving them 'false information', and even a punch in the face from Raichi.
Yet you, Team Z's manager and doctor, were treating his injuries with such care and gentleness. He knew he was a bad person, but deep down, he wasn't truly selfish. All he wanted was to fulfill his dream of being the world's best striker.
"Why are you helping me?" Kuon soon spoke up, unable to resist his growing curiosity.
He was now distant and standoffish to the others, nothing like the caring and loving Kuon that he had been, but something about you just seemed to make his gentle tendencies come back.
