The era when people have to buy emotion is coming.
Though the article takes up the game as the specific phenomenon in Japan, the game is more common than I expected.
It's because Japan's people have stereotype that white and black people are good at finding partners.
But, in fact, the unignorable number of people in the United States and Europe are devoted to romance game, if not Japan.
In the near future, teachers will have to teach how to get in good terms with opposite sex.
