It wasn't the response Kara was waiting for: «Aren't you happy, my raven-haired boy? You should be thankful for this incredible honor! Anyone else would give all his treasures to be my sex slave, and you dare to frown upon my offer!» – Kara yelled angrily, throwing her other shoe at her new husband. She would gladly tell him her real title in the demon empire, but even the son of a goddess mustn't find out her ancestry.
