Ueno works at Gotanda Kingdom, a love hotel in Gotanda, Tokyo. It is an environment where it is easy for human nature to be laid bare and he usually hides and is discrete for customers’ sake. However, Ueno objectively sees the true feelings of men and women who have difficulty understanding each other and appeals to them by offering sound advice. He rather sadistically teaches them tricks to be popular regardless of gender through the experiences he has analyzed.
