„Tsk.." Oikawa unconsciously clenches his fist while putting his phone away. He starts falling into a sprint only to weakly hum to himself the next moment to cover his anger, when he notices a young mother with her kid passing him by.
„That guy's weird. " He hears the kid say to his mother, seconds later, when his signature cover-up smile still hides the heat he is actually feeling boiling inside. Just how damn fast had his former kohai evolved? And who had pushed him up to this level? He didn't care if Karasuno won. He didn't care enough the see the end of the game, that was. At least that was what he tried to tell himself. He loathed his kohais new team for the most ridiculous reasons. He was well aware of that. Below his ever so present smile and pretend believe in his own team, he also held a grudge for his junior teammates. 'If it weren't for them…' he thought to himself, '..maybe Kageyama would have joined their team..his team. Maybe then, he would have gotten a second chance…'.
Below his smile, he gritted his teeth. While what happened between Kageyama and his former team at Kitigawa Daiichi might have been part of the reason for the younger ones choice not to enrol at Aoba Johsai, he knew the main reason was himself. And he hated himself for it. Besides successfully fooling others with his cheerful, charismatic and fame-driven ways only his best friend Iwazumi could tell how, for the last three years, Oikawas mind regularly spun around that faithful day. The day he broke something in those big blue eyes that fixated on him with so much admiration, he just couln't take it. That day that ultimately caused Kageyamas regression into the blank-faced king, that was deserted and despised by his subjects.
His train of thought abruptly stopped when he noticed he had arrived at this door again. He had stopped there a couple of times over the last years. Always with the urge to do something. To undo something. He never did. But it led him to bump into his junior every now and then. Greeting him with that belittling smirk and a sarcastic comment each time, he treasured every encounter with the genius setter as much as they threw him deeper into despair. He knew his actions caused Kageyama to hate him even more. And it cut him deeply, whenever he could catch a glimpse of fear in the younger boys eyes. Ashamed, Oikawa looked to the ground.
It had uplifted and hurt him at the same time when he saw that fear diminish gradually over time, since he was with Karasuno. Even up to the point where Tobio would be brave enough to come to him for advice about this little despicable redhead of his. Even though he felt relieved that his kohai was finally healing by getting over this past, their past, it destroyed him when he understood it meant he was getting over him, too.
He despised that genius. He feared that genius. He wanted to crush him. He wanted to be the one to bring out everything in him. He wanted to be the one Kageyama smiled at, breathlessly sweating, full of joy with those innocent yet intense blue eyes. This damn genius. His genius. His little kohai.
"Damn you are pathetic, Crappykawa", he hears his best friend scolding him.
"Nah, Iwa-chan..", he turns around, playfully winking at his teammate. "Don't be so meeean~"
"Stop it, Shittykawa. Don't you think you've been sulking over what happened long enough? If you really want to change things.."
"I'm going to Tokio."
"You wha—" Iwazumi looks at his friend. Oikawas playful demeanour had faded and he returned his look with a stern face, quiet determination in his eyes. A look he would only rarely see, usually during a strenuous point in a match, only for a few seconds, usually too short for anyone else to notice. It was a look that made clear there was no room for arguing. His friend had finally made a decision.
He sighs and smiles at his childhood friend. "Just.." '..don't hurt him', he thought. "..don't mess with their game."
