Determining to be with someone you haven't known before requires courage.
What's more, Gu Xiaonuan had someone she liked before, and that person wasn't Si Yuchen.
Their twisted fate started because of Shen Biran's illness; otherwise, Gu Xiaonuan might not have even known who Si Yuchen was.
It's unclear why fate arranged it this way, but for the sake of their child, Gu Xiaonuan naturally accepted this best option.
Their being together would yield good results for the child, or for them both.
Gu Xiaonuan didn't know that Shen Biran was very supportive of her marriage with Si Yuchen.
It seemed like their being together was particularly fortunate for Si Yuchen.
Shen Biran was also very fond of Si Yuchen, a sentiment that Gu Xiaonuan gradually discerned.
