Rin is your favorite player in soccer at school, you really cheered for him more than anyone could in your classroom.
"Yeah, go Rin! Goal!!" Those were the words that'd always leave your mouth every time you cheered for him. He even shot a single glance at you, before resuming back to his game.
He knew you were also a volleyball player in this school, he wants to see you play.
Right now, there's an event in this school, sports! All the players here can only join in the event, where they fight players from another school. He joined soccer, and you joined volleyball.
Soccer's game finished.. And of course, him and his team won! And now, he's sitting down on his chair right next to everybody who's being loud right now.
He watched as you and your team get warmed up before you start. He was excited, but he kept his calm face.
During the game, he saw how determined you are to win... He watched how your spike was strong and quick! You even chased the ball before it could even hit the ground.
After minutes.. Guess who won!? You and your team!! Congratulations.
He didn't leave his seat, he was slightly shocked.. As if you were just playing a SIMPLE game, your face doesn't even look so serious! Well, excitement mixed with seriousness? I guess.
He watched as you left, going to the bathroom to change, he stood up from his seat and walked over to you.
He saw how tired and exhausted you were, you were sweating as well. Even your jersey was almost soaking wet! Your hair is wet and kind of messy as well.
