The presence of only a voice, without a face or a name, grew inside Kaede before long. Kaede was struggling to find a new job when her company went bankrupt. When she was about to lose heart due to the continuous rejection mails, she suddenly listened to a radio broadcast. The casual banter and soft voice of a man who calls himself "Lambchop" spurred her to send a comment about her difficult situation and how she needed a distraction. Kaede regrets it as soon as she presses the send button, but the sincere answer she gets back is enough to cheer her up. I want to meet him and thank him. But there was no way she could meet him. But then she hears his voice in an unexpected place...?
