**Chapter 81: Harmony of the Heart**

As Kageyama lay on his bed, listening to his favorite song, he felt a sense of happiness that he had never known before. He was no longer just a volleyball player, but a person with his own interests and passions, and he was grateful for it. The music seemed to have awakened a part of him that he never knew existed, and he found himself wanting to explore this new side of himself. Oikawa, who had been quietly observing Kageyama's transformation, decided to take a step further. He walked into Kageyama's room, a small smile on his face, and said, "You know, I've been thinking... maybe it's time we started a team playlist." Kageyama's eyes snapped open, and he sat up, a look of surprise on his face. "Really?" he asked, his voice filled with excitement. Oikawa nodded. "Yeah, I think it could be a great way to bond as a team. We could share our favorite songs and create a playlist that would get us pumped up before a game." Kageyama's face lit up, and he nodded enthusiastically. "That sounds amazing!" he exclaimed. The two of them spent the rest of the day creating a playlist, with Kageyama introducing Oikawa to his favorite artists and songs. They laughed and joked as they worked, and for the first time, Kageyama felt like he was truly a part of the team. As they finished the playlist, Oikawa turned to Kageyama and said, "You know, I think this could be just what we need to take our game to the next level." The next day, Oikawa gathered the team together and introduced the new team playlist. At first, some of the team members were skeptical, but as they listened to the music, they began to get into it. They started to sing along, and even dance, and for the first time, they felt like they were truly a team. As they walked onto the court for their next game, the music was pumping through their ears, and they felt a sense of unity and purpose that they had never felt before. They played with a newfound energy and passion, and their opponents were caught off guard. The game was intense, with both teams fighting for every point. But Kageyama and his team were unstoppable, their music-fueled energy propelling them to victory. As they walked off the court, exhausted but exhilarated, Kageyama turned to Oikawa and smiled. "That was amazing," he said, his eyes shining with excitement. Oikawa grinned back at him. "I told you it would work," he said. "Music is a powerful thing, Kageyama. It can bring people together like nothing else can." Kageyama nodded, feeling a sense of gratitude towards Oikawa for understanding him. He knew that he had found a true friend in him, and he was excited to see where this new journey would take them. As they walked off the court, Kageyama couldn't help but feel a sense of pride and belonging. He was no longer just a volleyball player, but a part of a team that truly understood him. And as they walked into the locker room, the music still playing in their ears, Kageyama knew that he had found his true harmony.
