Joke: Does the school prohibit "love between men and women" or "love"?

I guess: The original intention may be to prohibit love, regardless of men and women, women, or men and women. But love between a man and a woman is easier to detect, and if it is too close, it will be exposed. On the surface, it is difficult to distinguish between good buddies and good gay friends between men, and the same is true between women. Therefore, it is basically forbidden for men and women to fall in love.
