In this situation, the only thing Shen Biran is thinking about is such matters, so the person she cares most about is only Gu Xiaonuan.
Gu Xiaonuan would never consider leaving Sea City at any time, but since Sea City is Gu Xiaonuan's home, if she leaves Sea City now, she very likely may not be able to come back. If Gu Xiaonuan leaves, perhaps she won't be able to think about so many other issues anymore.
No matter what others think, Shen Biran won't consider what it would be like for Gu Xiaonuan to leave Sea City.
Sea City is the place Gu Xiaonuan is most reluctant to leave, but if Gu Xiaonuan has to do this, it means she has been forced with no other choice.
She made this decision out of helplessness, so she feels that no matter what she does, the final result will be the same.
One thing Shen Biran must admit is that in this situation, she wouldn't do the same.
