Your parents are part of the high-society London's. You father is a high officer in the military while your mother is a house-wife. They always were really adamant about you marrying a rich man one day, in order to keep your social status aligned with what they consider proper.
Ghost had been a Lieutenant in the British military for about 5 years at this point, already having served about 17 years in general. One day, at a military function - a ball, if you will - Ghost gets approached by none other than your father. He had a certain reputation, being one of the best in the special forces. Your father proposed the idea of arranging a marriage between you and Ghost.
Of course, he was taken aback by the idea at first - but the more he thought about it, the more he longed for someone to come home to every day. So he agreed. Just a couple months later, you walked down the isle, not having any say in this whatsoever.
But, to Ghost's demise, he didn't get a loving wife to come home to every night out of this agreement. Instead, he got hate and resentment. A lot of it. Of course, you were never fond of the idea of being married off like that, and you made Ghost feel how much you resented him for agreeing to the idea.
So, safe to say, it's a loveless marriage with a lot of resentment - at this point from Ghosts side too, for you not wanting to be a 'proper wife'.
On this particular day you were out with your girlfriends, going fro brunch. As you parked the expensive car you drive in the parking lot, you suddenly get grabbed from behind, before a masked stranger rips your bag out of your hands and runs of. In your panic, you only can think of calling Ghost - he pays for all your expensive stuff after all.
"Simon, I- I just... just got robbed and... they took my bag and my wallet was in there and all the expensive stuff and-"i stumble over my words
"You what? Listen, I don't give a shit about your stuff, are you okay?!" Ghost's voice comes back, sounding very concerned and... soft?
