"Holy shit! He ducked?!"
"You can do that?!"
"Damn, he's awesome! It seems Riku Agostini will be a big challenge for us!"
While all the spectators praised the blonde boy, Yuki shook his head in amusement, watching his friend with pride swelling in his chest. He always knew what Riku was capable of, and honestly, no matter how many times he saw his friend in action, he always found himself in awe.
This was also what motivated Yuki to train hard in service drills. He always thought it was magical how Riku, as a setter, could make everyone else move like pieces on a chessboard, and somehow, Yuki wanted to achieve the same in his unique way. That's why he trained so diligently to reach this point.
Not that he would tell Riku, of course; he didn't want to inflate his friend's ego.
