Synopsis: Married His Brother and Now He's Obssessed

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?
