Through the book, Ayla, who becomes a cannon fodder supporting role, will die at any time due to a strange disease. In order to save her life, she took the initiative to marry the elder brother of the male lead of the novel according to the setting in the book. Royden's body is filled with the blood and is feared by others, and he is being used by the empire. In order to protect his brother's safety, he could only keep a low profile and bear it. Originally, it was just a contractual marriage in which benefits were exchanged, but at some point it became a two-way rush to redeem each other.
How lucky can one girl be? The cure to my illness is to marry a handsome duke, and I don’t even mind his half-demonic bloodline. I love his family, my family loves me, and once society gets to know the Blightons, I’m sure they’ll love them, too. Now, if I remember the novel's storyline correctly, all I have to do is stop his little brother from getting bullied and make sure he meets his one true love… and then we’ll all get our happily ever after, right?
