End notice. I decided to quit the cas. The reason is that work is busy and fatigue of human relations. Since it is not completely lost, it appears occasionally in a certain frame. Thank you very much for the person who has made good friends. I know a lot of world that I don't know, and the world view changed at this age. I would like to delete the link and get the link exchange. Thank you very much for your poor conversation and singing. It was a happy time.
