Han Ling'er will eventually understand a truth: what doesn't belong to her will never be hers.
No matter how many tricks she uses, the man she manages to snatch in the end may not truly grow old with her.
This is also why Gu Xiaonuan thinks Han Ling'er is deluded—this woman is truly ridiculous.
When Gu Xiaonuan was just a child, she understood that a lover who can be taken away is not a true lover.
When Gu Qingyuan was snatched away by Zhao Ying, Shen Biran's attitude was also very clear.
Since he has been taken away, there's no need to try to get him back or forcibly keep him.
Shen Biran sees it clearly, which also made Gu Xiaonuan understand in advance that this is how relationships are.
If we must say Gu Xiaonuan feels some sympathy for Han Ling'er, then that's true.
She truly pities Han Ling'er, extremely pities this woman who has nothing, yet still has the courage to snatch a man from Li Lu.
