You'll have to ask her yourself

"You filthy bastard! How dare you!" Ashroth shouted and punched toward Max.

Whoosh!

His peak four-star demon energy surged out of him, transforming into a palm and flew Max like a shooting star.

When he met Amara a while ago, he had sensed a faint, masculine scent on her body and her expression wasn't also quite right.

This made him suspicious, but he wasn't concerned about it. In fact, he was happy that his sister had found someone to her liking and just wasting the prime of her life.

However, as he walked out of the villa, he suddenly thought that the scent seemed a little familiar. After thinking about it for a moment, he realised who the scent belonged to. It was that human's scent.

This realisation made him angry. He wouldn't mind if the person Amara liked was a demon, but a human was out of the question.

Therefore, he went to Amara's servant quarters to find and kill Max, but didn't find him there.
