Gu Xiaonuan had plenty of time to discuss the divorce issue with Si Yuchen, but there's one thing: although she had a lot of time, not all of it could be wasted on Si Yuchen.
Marriage is a matter of mutual consent, and divorce is the same.
When they got married, there was a written contract in black and white, but now the first to breach it was Gu Xiaonuan. However, there was some justification for Gu Xiaonuan's breach.
The root of their divorce issues, in the end, was Si Yuchen.
Si Yuchen's mistake caused Gu Xiaonuan to lose their child, and at the same time, they lost all their past memories together.
Gu Xiaonuan didn't even think that her past self would be with Si Yuchen, doing such a foolish thing.
Gu Xiaonuan actually faked a marriage with Si Yuchen just so Shen Biran could get good treatment? Looking back now, Gu Xiaonuan couldn't even imagine it.
Was she really that bold? Now that Si Yuchen refuses to divorce her, she realized how foolish she had been.
