While Yuki was forced to rest earlier, on the court, all of his teammates were struggling to regain the foothold without the glasses boy's presence there. They were still in a daze, taking their time to recover.
Their reaction was understandable. Yuki was their best player in the first set. Not only did the glasses boy lead the team to the win with his ten consecutive ace services at the end of the first set, but he was also the team's best defender with his timely reaction that saved the team so many times. Not just that, whenever he joined the attack, he would also be an important member who all the opponents would put their eyes on.
So, even though they just won the first set, losing Yuki was definitely a price that was too heavy for them to pay.
