That night at the Holy Banquet, the Arrow of Desire struck both the divine prince Cassius, a descendant of Zeus, and his father, Theron. If they didn’t mate before the moon set, their divine power would implode, shattering their very essence. In my past life, I had secretly loved Cassius for ten whole years. So, when he grabbed me, his body burning up, I didn't say no. After one wild night, I was carrying his thunder-blooded child and successfully married into the divine palace. But after the wedding, he was ice-cold to me. He was convinced I had stolen the Arrow of Desire, all for the sake of marrying into divinity. Even after I gave him children, he never claimed me as his wife before the gods. He saved all his tenderness for his one true love—the holy maiden Lyra, who was forced to marry into the Sea Realm and eventually died in a storm. Later, I was branded as "jealous and wicked," scorned by all of divine kind. So when my children’s overwhelming lightning magic went out of control, no one came to help. My babies and I were consumed by that arcane tempest. When I opened my eyes again, I was back on the night he was shot. The young divine prince Cassius, burning with heat, reached out to me with desperate hunger. But high up on the throne... His father, Theron—the beautiful, ruthless God King who had ruled for centuries—was also losing the battle against his own searing desire. Everyone expected me to throw myself into Cassius’s arms. But this time, I gathered my skirts, strode past him, and sat right on the God King’s lap.
