The appearance of Lu Xiao caused a drastic change in the relationship between Gu Xiaonuan and Si Yuchen.
This was not because the relationship between Gu Xiaonuan and Si Yuchen was unstable from the beginning, but rather a possibility.
If they don't get divorced, their feelings could grow stronger.
But if Gu Xiaonuan decides to divorce Si Yuchen because of Lu Xiao, then their relationship wouldn't need to continue.
In any case, Gu Xiaonuan must be resolute, or she would regret it in the future.
Gu Xiaonuan herself should also think clearly about what she wants, or how she wants her relationship with Si Yuchen to be.
Their relationship has reached a point where there should be some certainty, otherwise, no one can accurately say if it will affect their future interactions.
Lu Xiao's appearance is more like a test, testing whether their feelings have the possibility to continue, and testing Si Yuchen's feelings for her.
