This saying by French author Honoré de Balzac means that when people are in love, they often try to delude themselves and put up a false front to make the relationship work. They may even deceive the other person, unknowingly or unknowingly. Love often leads people to be dishonest and, at the same time, makes them believe that it’s acceptable behavior. In the end, the relationship didn’t lead to a sustainable happy ending, which the world finds so alluring, which is why it’s called “a romance”.
