Claudio Serafino [HeadCanon]
This is a request, but I opted for this format so it would be cleaner and easier to search for. Enjoy!
Claudio does not fall in love easily; he is very distrustful and always puts his mission first. This changes when he meets you, and his growing love for you turns into a silent pain, overshadowed by the loneliness that his duty demands of him.
After missions, he stays a bit longer, making up excuses to be near you: he checks his equipment, offers to drive you, all with a tenderness that contrasts with his usual efficiency. You notice the small cracks in his composure: how his fingers brush against yours a moment too long, how his gaze softens when he thinks you are not looking. However, he never speaks of it, fearing that naming that feeling would turn it into a weakness he cannot hide.
Claudio will never explicitly say he is protecting you, but he will always appear in the places where you are without you having told him where you would go. When you ask him how he found you, he says something banal like "due to residues" and changes the subject.
The only way he expresses fear is through excessive orders: "Do not go out after dark," "Do not talk to strangers who give off 'wrong vibes,'" "Stay where I can see you." If you ask him why, he will say it is so as not to "complicate his exorcisms" or because "cleaning up your mess would be annoying."
Due to his work, he almost never cooks, but he shows up with food from exclusive restaurants or, if you are thirsty, he prepares "infusions that coincidentally happen to be your favorite flavor." It is a veiled love language; every act of care comes with a practical excuse, never a sentimental one.
For someone who denies emotional bonds, he is very jealous, but not in a vulgar or theatrical way. He places himself between you and the other person with his perfect exorcist posture, smiling with that arrogance of his, and simply talks about his achievements. In private, he never reproaches you, but he does ask questions if you are interested in that person; even if you tell him no, he does not relax.
I feel he is a bit paranoid; since he saw that demons can possess even the strongest, he performs a ritual to ensure no entity has touched you while you sleep. He does it with such elegance and feigned annoyance that it seems he is doing you a favor, but if you try to skip it one day, he becomes unbearably insistent.
He avoids touching you after using his abilities; he is convinced he could "contaminate" you with dark energy residues.
Claudio has recurring nightmares where he becomes what he vows to destroy, and in those dreams, you are always the one who has to stop him or run away from him. That is why he secretly trains you so you can defend yourself from him, and that is why he maintains a sometimes abrupt emotional distance: it is not contempt, it is genuine terror that his arrogance and power will consume him and you will become his first victim.
Obviously, he will not apologize, but you are not foolish enough not to realize he is protecting you, and you love him so deeply for that very reason.
