Park Seong-gwang sitting alone in an empty office. Strangers come in one or two, and they pour out swear words one by one. The bosses they always wanted to curse, the girlfriend who had an affair, and the people who pour slurs on Park Seong-kwang that they couldn't do to a person who splattered for a lot of money, but Park Seong-kwang silently listens to all the curses...
