Tirade

Silver eyes, ancient and timeless as the starlight itself glare at her.

"What," his voice is rough from sleep and laced with venomous fury. "What do you think you are doing?" 

Confronted with those eyes, looking at her as if she had been a stranger of sorts, with judgment that brings back all the burden of guilt that had eased. Seol had almost deluded into absolving herself of her actions, with one critical look of those dazzlingly silver eyes she finds herself crushed under its weight once more.

He knows. She thinks uncomfortably. It is unlikely that he had heard what had transpired outside the tunnel. The grand princess had not been quite exactly, but still Seol doesn't believe Seo had been conscious enough to comprehend what she had done.
