Male and female colleagues used to have a good impression on each other. Men invite women to dinner, and women make it clear that they like men. They invited men to the movies and found that men were shameless and wanted to eat soft rice. Human nature has weaknesses, and what cannot be obtained is always the best. Once you have it, you don't know how to cherish it, and you will recklessly squander each other's tolerance and dedication.

So, after two people get familiar with each other, they both take it for granted, no longer attach importance to each other's existence and can't see each other's efforts.
