Country F was different from other countries. The countries with royal families in the world were originally different. Most of them were retained as national symbols and did not have any real power. They only existed as mascots.
Therefore, their succession to the throne was very stable. It made no difference who became the king. The others could continue their current rich life. It made no difference if everyone had to attend official affairs. It could only be said that the king would be more tired.
However, the king of Country F was the true ruler of a country. Although there was a president politically, the army was firmly in the hands of the royal family.
Therefore, it also caused the classes of Country F to solidify. From top to bottom, there was still a difference in status in their minds. The people also respected the royal family.
