A guy name Key has a special talent – playing the piano. He’s a very poor guy, so he doesn’t have a piano. During recess in school, he always goes to the piano room with his score sheets and started playing the piano. One day, when he was playing, a group of boys saw him and told the teacher. He got scolded and was ban from the piano room. The girls from his class also hated him and made fun of him. They tore his score sheets, making his efforts wasted. 

But Key did not give up hope. He rewrote his score sheets again, even though there were lots of them. When he re-read his score sheets, he found that there was a missing part in it. He remembered back, and he had left the teared score sheets at the piano room. He had no choice but to go back there, really wanting to finish the score sheets. 

When he went back there, the bullies saw him and snatched the teared score sheets. They tear it into pieces and threw them into the dustbin. They also told the teacher and the teacher banned Key from going to the piano room forever.

However, one of the girl bullies gave him a note, with the missing part of his score sheets. 

She started falling in love with him, but she still hated him too. What will happen when she realises that she had fallen for Key? How will Key feel? Most importantly, how will her friends, Key's bullies, feel?
