Arthur immediately grabbed Luna's hand to stop her from harming him any farther by the broken piece of coral glass in her hand.
She has already cut a long stroke from below the sternum to the lower abdomen of Arthur's left side.
But thankfully the injury isn't deep or severe although it's quite lengthy. Because of Luna's weak body, she only could manage to cut the external abdominal fleshes.
Arthur forcefully snatched the piece of glass from Luna's hand and threw it away. He doesn't know what to say as Luna left him speechless by her vicious inhumane behavior.
"How could you..." He made an indistinct sound as he couldn't complete his sentence with his quivering lips.
Luna kept staring at Arthur with her expressionless gaze that failed to hide her malicious satisfaction.
"Does it hurt…?.." she asked mysteriously.
