Gu Xiaonuan doesn't really hold grudges, because every time things develop to the end, she will find that everyone has unavoidable reasons.
For this or that reason, in the end, no one is truly a bad person.
But Gu Xiaonuan can't bring herself to forgive Lu Xiao, perhaps because Lu Xiao has had such a profound impact on her, that even now she cannot truly and generously forgive him.
Gu Xiaonuan can never become truly loving with Lu Xiao as father and daughter, there is simply no such possibility.
This is an established fact from the past, leaving no opportunity. Gu Xiaonuan is so stubborn, especially in this regard, her stubbornness is inexplicable.
Li Lu also doesn't understand why suddenly there is a Lu Xiao, and this middle-aged man is Gu Xiaonuan's biological father.
Being friends with Gu Xiaonuan for so long, how could one have thought, Gu Qingyuan is not her biological father.
