But love never reasons, respects principles, or discusses conditions.
When it draws near, it never conducts a preliminary review: whether the couple's ancestors had been mortal enemies for generations, whether their ages, backgrounds, personalities, and appearances match, whether there are any actual or potential fundamental conflicts of interest, whether they'll be vehemently condemned by people around them, or even opposed by the voices in their own hearts.
Studies have even found that if a man and woman related by blood meet for the first time without ever having seen each other and without knowing their kinship, they might fall in love at first sight. Whether this is an inexplicable trick of genetics or a cruel joke played by fate remains a topic of debate. What often determines whether two people can stay together for a long time are ethics, morality, comparisons, and evaluations, not love itself.
