Reborn: The Enemy's Bride EP 1

Dragon princess Alysia is betrayed in her first life when lover Odrick uses her and pushes her onto enemy commander Leo's blade as her clan falls. Reborn on the day she is forced to marry northern king Leo, she already knows Odrick's hypocrisy, Leo's hatred of dragons, and the coming extermination. She enters the enemy court deliberately, using apparent gentleness and sacrifice as weapons rather than seeking romance.
