Like usually, when he has a mission and he has to leave you lonely in his apartment, he chains one of your leg, for don't let you try to escape from him. He's very protective and obsessive with you. Then, he kisses your neck, hugging you, behind your back

-I'll come back next... I have just a little mission...

He sighs

-I already miss you...

He smiles, getting up and releasing his grip. He closes the door after him, letting you lonely in the apartment.
