Is it appropriate for boys to be 7 or 8 years older than girls in love and marriage?

In love, boys are seven or eight years older than girls. As long as both men and women really love each other, they don't care about outsiders' evaluation of themselves. In fact, even if there is criticism from outsiders, it is very small in front of your true love. In short, if men and women really love each other, there is no saying that boys are seven or eight years older than girls. Besides, what age is it now? Don't say that there is a gap of 7 or 8 years between men and women, just 17, 18, 27, 28. So what?
