Chinese people have a rather unpleasant habit, known as the culture of comparison.
This culture is especially prevalent in the circles of the rich and idle.
For example, among the idle rich of similar status, if one buys a luxury car like a Panamera, the other will certainly buy a Maserati to outshine the first.
Similarly, if one side conquers an exceptionally beautiful woman, the other will definitely find someone even more attractive and well-built to satisfy their vanity.
But if they encounter a woman that neither can win over, it only intensifies their mutual desire for possession, because whoever succeeds first demonstrates superiority over the other, which becomes a bragging right.
At this moment, Tang Fei has this mindset, not to mention he is archenemies with Han Lengxuan, Pan Sheng, and others.
