"This is so boring!" Kukai groaned as he emptied another trashcan.
"As guardians it's not like we really have a choice." Amu said while the two left another classroom.
"Yaya sure is lucky she missed today and even the Charas are probable having fun right now."
"Come on Kukai stop complaining." The two guardians were quiet for a moment as they continued their job, but as they walked down the hallway the duo stopped short when they heard the low, but clear notes of a piano. The guardians looked at each other before they shrugged and quietly walked toward the slightly ajar door. The two guardians peeked threw the crack in the door and their eyes immediantly widened at what they saw. Both quickly retreated from the door.
"Was that Yaya?" Amu whispered with confusion in her voice. "I didn't know she played the piano and so well."
"I didn't know either." Kukai said slowly as the soft notes gently came to an end. Both guardians looked towards the door before softer music began to come from the room. The notes started soft and to the boy the notes were easily recognizable.
"It's that song." Kukai whispered to himself as he looked back in the room.
"What song?" Amu asked quietly.
"The lullaby my mother would sing to me whenever I had a nightmare." The boy responded as he closed his eyes and leaned closer to the door. "My mom must have sung it to her when she babysat Yaya when we were younger." Kukai's voice held a new tone in it and when Amu looked over at him, his eyes were intently watching Yaya play, Amu saw something new in his eyes something that told her she had one less crush to worry about. Amu looked away from the boy and she slowly closed her eyes and listened to the beautiful music. Kukai looked at Yaya, the girl he once considered a little sister and he saw a different person sitting on the ebony piano bench with her eyes closed, as the sunbeams danced in the air. The only reminder of the girl's usual personality was her baby Chara who was dancing around the room. He felt his heart beat faster as she continued playing a song that he had heard countless times in his childhood, a song of comfort.
"Hey guys what are you doing on the floor!" The music stopped abruptly and Yaya immediantly turned around and saw the two guardians staring at her. The two people at the door immediantly saw Yaya's eyes widen in shock.
"Kukai! Amu! Did you finish your work?" The two guardians finally turned toward the fast approaching voices to see the rest of the guardians and all of the Charas making their way towards the duo.
"We um got caught up." Amu finally said as the approaching group stopped in front of them.
"What do you mean you got caught up?" Tadase asked.
"We saw some kids with ice cream and we asked for some. Then we ate to many, so we decided to lay on the floor." Kukai responded scratching the back of his head. Amu gave him a confused glance, but she kept quiet. Tadase and Nadeshiko merely chuckled at the explanation. The group began to walk down the hallway forgetting all about their guardian tasks. Kukai took one last look in the room with the piano to find it empty. You would have never known that the room once held a girl and her guardian if not for a bright red ribbon lying next to the piano bench.
