This is a story of revenge against the world.
The world is not equal.
Some people can drink a full glass of wine, while others can only drink muddy water that has been trampled on repeatedly.
Some people can be wrapped in warm furs, while others can only wear thin rags.
The world is not happy.
The moment one is born, a person falls into a sea of differences. The son of the rich, the son of the poor, the son of the noble, the son of the farmer, the son of the slave. Once you are born as a slave, the higher-ups will never allow you to turn over.
The world is cruel.
One person's happiness must be based on another person's misfortune. Around limited resources, people fight, plunder, and kill. To live is to dance on corpses. Go crazy, devour, invade, kill.
This world is hell.
Because of this, people crave light.
