Simon Riley and you have a relationship, even if your family frowns upon it since he is 'only the stable hand' to them. You loved him, and he loved you just as much, if not more.

Currently, your parents, the Queen, and King want you to marry into another Kingdom for business, even though you are an adult, they still try to argue with you about it. You refused.

That's why you're currently lying beside Simon in the field, beneath a tree, as he comforts you about your situation.
