Person A (royalty) is happy with their life. They're happy with every aspect, except two. 

They can't marry - or even think about - the cute gardener (person b) that works in the royal gardens.

And, Person A is engaged, put into an arranged marriage.

One of the most important and oldest royal rules is that royalty can only marry other royalty or nobility. Which sucked for the Person A, since they had the biggest crush on Person B, and constantly made trips down to the gardens to visit them.

Will person b reciprocate their feelings?

Will the law change?

And, will Person A be able to end their engagement?
