Their reactions are strange and not at all what he would have expected. The moment Xingchen lowers Shuanghua, Fuxue follows. They are in tandem - two hearts that beat as one - and Zichen doesn't have any desire to fight or threaten his soulmate. Now Xue Yang on the other hand is a different story, though he saw, clearly, that Xingchen is protecting him.

Why?

"You know him." so this isn't some devilish ploy? How -

"I feared he had lied to you and was using your blindness to trap you." he has not sheathed Fuxue, but the blade is motionless at his side, "Xingchen, I have been searching for you. I was -" his gaze darts to Xue Yang, searching his face for any sign of mockery, "...scared. For you."

And himself. Without Xingchen, everything is flat and dark. He has his soulmate's eyes, but he does not enjoy his sight.
