Cecilia Winter is the strongest paladin in the Kingdom of Letnia. She was born to live to protect others, burning her own life in every battle. She never felt that she was worthy of being loved, because the whole meaning of her life was to save all living beings from fire and water.
Ren Aster is the most troublesome prince in the whole kingdom. Arrogant, willful, and vicious, he has a hundred ways to make people speechless. No one knows that his willfulness is just a disguise, and no one knows that the sacred artifact "Star Crown" that can subvert the world sleeps in his body, and every time he uses it, his lifespan is shortened.
An unexpected abyss monster attack caused Cecilia to burn three years of her life to protect Renne. The king assigned her as Ren's personal guard in the name of "protecting the heir." One was a knight who didn't understand selfishness, and the other was a prince who didn't dare to be sincere. The two people who were forced to be bound began a long process of pulling and getting closer.
In the most childish way, Ren taught Cecilia little by little: a person's value does not need to be proved by injury, and the prerequisite for loving others is to learn to love yourself.
And when the shadow of the abyss falls again, and when two people are willing to burn their lives to protect each other, they finally understand that true love will not make the person who loves them sad for themselves, and their first principle should be to live well for each other.
