I'm gonna have to re-read this cause i remember the spoilers but I dont remember the story. I binged too many romance stories, so i cant remember half of these.
EDIT: after re-reading it, it makes more sense if she ends up with Jade, he definitely likes her and she likes him. And it would be cool if a commoner would win, cause she would have higher status as the Grand Duchess // Prince Consort, (they switched it awhile back, and a Grand Duke is like the cousin of a king or uncle usually closely related to the current king and of Royal Blood) and can get revenge on those dumb bitch underlings
