Social Science
I don't want to be cheated, but I don't want to argue! Whether in your work or in your private life, do things happen in a way that doesn't suit your own will, or do you feel somewhat fuzzy? You can't speak well enough to push your own will, and above all, you worry about the human relationship after that. For such people, Hiroyuki teaches "how to speak and convey people well."
