The Ice Dragon's Defiant Trophy

I am the weakest of the Fire Dragon bloodline. Born without a Beast. He is the heir to the Ice Dragon throne. He is cruel, unbeatable, and has long hated me. The monster-conqueror plans to make me his toy and turn my life into Hell. But bringing me to my knees won’t be that easy!

In the text there is: a dragon, a властивий (dominant) hero, from hate to love, a true pair, a happy ending!
