There's absolutely no need to care why Shen Biran would have such a reaction. Because even if Gu Qingyuan wanted to explain for himself, there would be no chance for that.
Gu Qingyuan seemed to forget one thing, which is that doing this would almost never lead to any results.
He appeared to have helped Lu Xiao a lot, but it's estimated that even Lu Xiao himself cannot get the result he wants.
Lu Xiao seems to have gained everything, but who knows if he can really get everything he desires?
If he can't get it, how should it be resolved? And now the situation is what it is, Shen Biran doesn't need to worry or consider anything more.
Shen Biran's feelings for Gu Qingyuan are just like that.
Their relationship was completely shattered because of this, with no chance or possibility left.
Perhaps it will still be so, but there really is no chance now.
