Faded black ink (слэш)

It was no surprise that one day a letter fluttered into Stephen Strange’s home offering him a job at Metro General Hospital in New York. As the head of the surgical department.
Within two days, Stephen had packed his bags, signed the contract, and given notice to his landlord. There was nothing holding him back, no partner, no commitments. At most, his colleagues would miss him professionally; he had built no personal relationships with them.
The new job came with a better apartment and he had just put a down payment on a new car - a sports car.
Nothing stood in the way of a brilliant career.
Until he met Tony Stark, head of the Italian mafia and underground boss of the city.
