Since the two men saw the problems between them from the beginning and agreed to divorce, even if Yu Huanshui finally succeeded, it had nothing to do with Gan Hong. Gan Hong didn't take a fancy to his money or his name from the beginning. If we want to talk about financial resources and power, it is obvious that Yu Huanshui climbed into Gan Hong's house, which also shows that Gan Hong did not take a fancy to his money when he married Yu Huanshui.
If a woman chooses to marry a man, either because he is rich or because he is kind to herself, then why should a woman stay with a man if both are not desirable? Therefore, Gan Hong divorced Yu Huanshui because the problems between them could not be mediated, so even if Yu Huanshui reversed in the plot, Gan Hong actually wouldn't fluctuate. Now that we are separated, I wish you good luck.
Moreover, after being separated from Yu Huanshui, Gan Hong and her ex-boyfriend got the certificate, which also shows that she has never let go of her feelings for her ex-boyfriend. This is a perfect ending. So even if Yu Huanshui was rich and powerful later, Gan Hong should be very satisfied with his present life, so the two men were completely separated, and the only connection was that they had a son and the same son.
Gan Hong has a new family and a new life, and Yu Huanshui has a new beginning and a new life. Therefore, whether it is muddling along as before, being looked down upon by people, or reversing life, with achievements, Gan Hong and Yu Huanshui are just strangers, and there is no intersection anymore.
