The key issue for Shen Biran is that she doesn't know how to deal with Gu Qingyuan. She has always been hesitant, unsure whether she should really harden her heart against Gu Qingyuan.
If she does harden her heart, it might require her to slowly think through the problem.
Shen Biran should also know what she should do at this moment.
Shen Biran feels such guilt towards Gu Xiaonuan, so regarding Gu Xiaonuan's happiness, she's even more cautious.
Anyone who can potentially affect Gu Xiaonuan's happy life is her enemy.
This is their biggest difference; Lu Xiao thinks that as long as he leaves everything he has worked for all his life to Gu Xiaonuan, she will forgive him.
Lu Xiao doesn't even know of Gu Xiaonuan's existence as a daughter, let alone save her.
She also couldn't immediately know that she still had a biological father.
In Gu Xiaonuan's life from childhood, she never expected such an outcome.
