Lu Xiao actually has his own difficulties, but his difficulties are definitely not because he can't explain the problem at hand.
Lu Xiao has his own ideas; he wants to convince Shen Biran and Gu Xiaonuan before he dies so that Gu Xiaonuan might inherit his estate.
He cannot let his inheritance pass to those who usually have other thoughts about him. To him, those people are not family but enemies. He has reached this point where he can't trust anyone anymore.
Shen Biran is worried about many things, but what she worries about most is Lu Xiao. If Lu Xiao were a simple person, it would be great, but he is destined not to have only Gu Qingyuan as a means.
He is sure to have more strategies waiting for him, and he can't say much more.
Gu Qingyuan's approach is understood by Shen Biran, but Shen Biran knows that these are all Lu Xiao's plans.
If we have to say it like this, then it's also Shen Biran's issue; it's Shen Biran who made Gu Qingyuan feel this way.
