Admiration ; a feeling of wonder, pleasure, or approval
Since he had started playing for Karasuno, Tobio Kageyama had had an incredible amount of revelations hit him…almost all nearly at once. It seemed that his mind was being constantly blown by the things he was picking up on these days.
Most importantly, he had learned to observe. When he was told by Suga-san that it was the setter's job to monitor the condition of his teammates, he had been caught off-guard by it. How had something so indisputably essential and basic escaped his mind? Since then, he had started to pay a lot more attention to his teammates. He was in absolute awe at how much he was learning about everyone through the simple act of observation. Recently, he had found himself increasingly intrigued by one teammate in particular; Shoyo Hinata.
He flashed back to the game they had played against each other during junior high. His team had properly trounced Hinata's by a large margin. Yet, he recalls having been absolutely stunned at the speed, agility and jumping height he had witnessed when Hinata had spiked that broad shot. After the tournament, Hinata had approached him; tears streaming down his face, and had 'informed' him that he would beat him on the court one day. He was ballsy, that one. Kageyama had wondered, just who the hell WAS that orange-haired kid?
And then, as if the betrayal he had experienced at the hands of his own teammates hadn't been enough, the fates had decided to put that same orange-haired kid in his path once more. At first, he had written Hinata off as just an overly excitable, loud, and obnoxious anomaly. He was just some kind of fluke with no real talent. He had obviously wasted his 3 years in junior high school, and Kageyama had no interest in playing with someone like that.
When he was told to play on a 3-man team with Hinata and Tanaka-san for the right to join the volleyball club, he had been absolutely infuriated. The shrimp couldn't receive a ball to save his own life. How the hell was he ever going to get anywhere with someone like that dragging him down?! He had vowed to ignore Hinata completely during the match and just feed the ball to Tanaka-san.
But then, something changed. During an exhausting rally at practice, he had angrily spiked the ball full power at Hinata after the boy had badgered him to keep going. He watched in admiration as Hinata chased that hit with every ounce of determination he had in his tiny body. Not only did the shrimp reach the ball, he also managed to receive it and send it his way for a toss. He had instinctively started to put his hands up for the toss. Kageyama will never forget what happened next.
Hinata was exhausted, way beyond his physical limits, and nearly wrecked. But the moment he looked up and saw that there was going to be a toss, he surged past the exhaustion and got back in time to spike it. That look of pure joy on Hinata's face was forever burned in his memory. He had never before witnessed such unadulterated delight, and it moved him. He had never been personally responsible for eliciting such a look from anyone, and it filled him with pride. Hinata practically sparkled with rapture. It seemed that he would burst from all the elation and Kageyama wondered how that little body could contain it all. It stirred some unknown feeling inside him. He wanted to see that look again, again, and again. He vowed to do whatever it took to make it happen.
That was the turning point. The beginning of all the highs, lows, the wins, the losses, and the inner turmoil Kageyama would come to face in that first year at Karasuno.
