Realization
DOMHALL WAS taken aback because of Louisanna's question. His lips parted as he wasn't able to answer immediately— nor think about anything that he could answer.
At that time, he was now curious about what kind of conversation Louisanna had with the angels.
He could detect using the effect of the contract on where Louisanna went, but since it was the Heavens, and a demon like him couldn't cross the line at all costs, he hasn't any idea what they talked about.
Unless Louisanna will tell him.
Which wasn't the case. Louisanna didn't speak about it, nor throw any questions about him— except the fact that he knew about Luna being an angel.
In a second he teleported Louisanna back to the Inferno, a sense of fear traveled onto his body, feeling afraid that Louisanna might hate him once she had a conversation with the angels.
But anger and fear weren't visible in her eyes— It was the opposite.
