Romantic analysis
Romance in a narrow sense comes from romanticism born in western Europe from 19 to the end of 19. Romance here refers to personal heroism that is not satisfied with the real world, full of expectation and pursuit for the future, ambitious and unwilling to degenerate. The emerging romanticism wants you to steal every little moment you can get together and share it emotionally.
Europeans believe that Beethoven initiated romanticism, because Beethoven did not give in to fate and dared to fight against aristocrats and fate. "I want to hold my destiny by the throat. It can never make me yield. " Beethoven is a Sagittarius, so later generations like to regard romance as the characteristics of Sagittarius.
