Tokura Wataru is a young guy who thinks he has figured out life. He is lucky to have a nice girlfriend and a nice job at a TV shopping show. All that, until he insults the anchorwoman and is moved to the company's dead end job at a call centre for complains. There, he meets the star of the call centre, Aoyama Kyouko. Kyouko and his new colleagues teach him how to understand people's feelings, as not everything is what it seems and many of the complainers calls for different reasons or just because there was nobody else to listen to them.
Both deal with a center for complaints and the people who try to resolve them. They have a brave heroine, who investigates every detail for the sake of resolving the real problem. In both there is a young, uptight persona who thinks he knows it all; and a boss who is too scared to take responsibility.
