Rain's Ambiance

It was about a girl who got her heart broken for the first time and shut herself up from the world until she met the sunny yet quite sadistic boy in her new school and started being friends with him. The smile that was washed away by the rain slowly comes forming her lips again when she hears the boy playing the piano during rainy days. Rain wouldn't be so sad when it's simultaneously mixed with the boy's playing of the piano. It gives a melancholic ambiance to a doleful rainfall.
