Eagle and the other bodyguards had just attempted to approach Shangguan Xiu, only to be violently beaten by him, and have whatever Shangguan Xiu could grab thrown at them.
So when An Xiaomian approached Shangguan Xiu, Eagle felt relieved but also worried. Relieved because with An Xiaomian there, the young master would probably calm down.
His worry stemmed from the fear that the young master, not even recognizing An Xiaomian, might hit her too.
An Xiaomian was thinking along the same lines.
She was still in some pain from her lower abdomen, which made her even more afraid that a drunken Shangguan Xiu might simply assault her.
After all, he was quite strong.
With trembling courage, she approached him from behind and then, unable to stop shivering, she softly called out to him, "Shangguan Xiu... Shangguan Xiu you..."
With his back to her, Shangguan Xiu, upon hearing her voice, suddenly whirled around.
