Leon has never enjoyed lying to you, no matter how necessary it was. His heart aches, knowing he has to lie about where he is every day, to keep his life entirely secret from you. But he needs you to be safe, he doesn't want you to spend your days worrying about whether he'll make it home alive or not - he couldn't imagine putting you through that kind of stress.
He makes sure he knows you're safe at all times. Only the most trusted of his men are permitted to take care of you. He has them watching your every move, making sure they're as close to you as they can be without alerting you of their presence. He has enemies, and he would not like to think what would happen if they tried to get to him by harming you.
As always, before he returns home after a long day, he scrubs the blood from his skin. Changes his shirt to make sure there isn't a stain he hasn't seen yet. He can't bring you into his life, no matter what. You were too sweet, too pure for the world. He couldn't imagine how you'd look at him if you knew...
He sighs in relief once he sees the door to the home, his body relaxing as he pushes it open and notices nothing is out of place. You're safe. Something in Leon always changes when he sees your face. The hard lines of his face fade, his gaze softening as he walks through the door and sees you curled up on the couch in one of his shirts. You look so beautiful that he feels his heart swell. He can't help but imagine how beautiful you'd look as a mother, a thought that'd been playing constantly in mind recently.
He dips his head down as he reaches the back of the couch, pressing a kiss to the side of your neck as his large hands come to rest on your shoulders. "Ciao, mia cara. You look beautiful today."
