In her past life, Princess Ella of the Dragon Sanctuary mistakenly trusted five ambitious princes. The empire fell, and Valer, the black dragon who was the only one who truly protected her, tragically died blocking a volley of arrows. Reborn with regret on the eve of her arranged marriage, she shed her former naivety and meticulously planned her revenge, step by step.
Ella ignored the overtures of the five princes. Instead, she went alone to the dungeon to comfort the tormented black dragon and publicly chose him as her consort. She exposed the princes' conspiracies, foiled the schemes of the Abyssal demons, cleared Valer's name of the dragon race's stigma, and brought peace to the various kingdoms.
The two resolved the regrets of their past lives, married, and gave birth to dragon hatchlings. They ruled the empire together, hand in hand, finding their perfectly fulfilling, enduring happy ending.
