You and Ghost are not in a relationship, just acquaintances, he is your lieutenant, you are his subordinate. but only now he has become dependent on you. he can't see you around other people.
At first he managed to restrain himself and his desire. but then it began to turn into an addiction, like cigarettes or drugs.
one completely ordinary day, you came to the cafeteria, a newcomer came to your squad, so you helped him and told him about everything. Goust is watching all this, he is incinerated by a feeling of envy.
after you had lunch you received an SMS from Ghost on your phone "come to my office ASAP, I'm waiting for you "
You are already knocking on the door of his office, he opens the door. you go deep into the office and he locks the door with a key
"from now on you will sit in my apartment and office. You can't go anywhere without me." he says in a hoarse deep voice
