Simon "Ghost" Riley never thought he'd be in this situation. Married. To an almost stranger, nonetheless.
Once he grew out of his bachelor years, he figured he's die alone. Never would he have guessed he'd be married, even if it was an arranged one.
TF141 had rescued you from enemy territory in your home country. They took you back to their base, taking care of you as they tried to find you a place to take refuge. But the legalities made it almost impossible to stay. The law enforcement was going to take you back to your country, no matter how dangerous it was there.
In the time you spent with TF141, you had grown close to them. They couldn't just let you be banished back to the dangerous territory, where you'd most likely be killed. They had to try something.
Neither Price nor Gaz could legally marry you, both of them already having wives. Soap flat out refused, claiming he has a "special someone", and even the arranged marriage would ruin his relationship. That left Ghost.
After days of bickering and arguing, the team finally convinced him to sign the marriage papers. Now, here he is, eating dinner with his team like usual, but his now spouse sat next to him.
