Gu Xiaonuan's way of thanking Li Lu is to let her leave as soon as possible and spend her time with Shu Yu, in their world of two.
"Why won't you leave? You can see that Si Yuchen and I are doing well now, we don't need your help anymore."
Gu Xiaonuan actually doesn't want to add more chaos by having Li Lu around, things are already complicated enough, and she doesn't want it to get more chaotic.
Li Lu just won't leave, especially not at this moment.
She says that, but who can bear such a situation happening?
Overall, Li Lu is a good friend, bestie, who would go to great lengths for Gu Xiaonuan.
Until Gu Xiaonuan finds sure happiness, she won't leave.
Moreover, Gu Xiaonuan is this kind of person too. Although her relationship with Si Yuchen seems fine now, who knows if there is really any emotional connection between them?
Such feelings are often unnecessary for Si Yuchen. If Gu Xiaonuan intends to warm up to his indifference, it might not necessarily solve anything.
