Kim Jongdae is a boy who plays with lightning and Han Yonhee is a girl who watches the lightning in the sky every night. Han Yonhee's loneliness is a rock and it is her and it drags her through the ground again and again and again. Kim Jongdae says he is sad because sad is an easy word and his mouth is weary; his entire being is weary. Han Yonhee makes Kim Jongdae laugh and smile and dance. She makes him happy. But happiness can only last so long for someone who has a sad mind. Kim Jongdae is a boy who played with lightning and Han Yonhee was a girl who watched the lightning. One day, the lightning stopped and the girl who watched the lightning and listened to the thunder was left to wonder why her world was filled with only the sound of silence. The lonely, lonely silence.
