Shen Biran is unsure of what outcome she will achieve by sticking to her decision, but as long as she persists, the result shouldn't be too disastrous.
Moreover, she understands the consequences of her actions. One could say she knows Gu Qingyuan better than anyone else, clearly grasping his thoughts.
However, Gu Qingyuan doesn't care about these things, and it seems he is not as clear about Lu Xiao's character and the degree of danger he poses.
Lu Xiao is extremely dangerous, and at this moment, if Lu Xiao intends to act, even Shen Biran would be powerless to stop him.
To stop him, she would at least have to understand his strength and cunning, and dealing with Lu Xiao is not a simple matter for Shen Biran.
That's why he has these thoughts now, and he is unwilling to feel this way.
Shen Biran has warned Gu Qingyuan, but Gu Qingyuan has never taken it to heart.
