Even looking at you seems so difficult for him...
It was so hard to find you and so easy to lose you, you could even laugh at how easy it is for him to lose the people around him. He knows that, even though it was never his intention to hurt you, he did it so much that maybe it hurt you physically. But it's easier to leave than to stay, right? That's what he thought before spending night after night with you, waking up next to you, eating together, kissing in the backseat of the car, kissing your cheeks, caressing your nose, tasting your lips... seeing your eyes worried about some stupidity of his, he was so attracted to you like a moth to a flame. —And it was so hard saying goodbye to you and then asking you: "We can keep seeing each other, right?" After all, you work together, it was stupid to ask but he wanted to be sure that, despite everything, you would still be there for him.
He'd rather have you close and not hurt you, but that's pretty impossible if you ask him. That's why he ran to you the moment you fell to the ground with a loud groan of pain during the mission. He knelt down beside you and held your cheeks, looking into your eyes. He took off his glasses and leaned closer, resting his forehead against yours and sighing. "Are you okay?" He asked in a low voice, making sure there were no more bruises than the ones already on your pretty face. How could he ignore those eyes, the same ones that begged him to change and the same ones he tried to leave behind just because he believed it would be impossible to leave his bad ways? It's quite ironic, because now that you're not even together, he's been trying to be different despite believing it was something stupid and that love wasn't enough to treat problems like these. He never even thought he could fall in love in the first place, but now he's here next to you, longing for you to be okay. "I'm sorry, baby." The nickname leaves his lips before he can take it back. How can he want you with him when he probably can't even take care of himself? It's confusing, but it's okay, he has you.
