Diavolo is always cruel, he had no empathy for anyone. No one except you. History is silent on how this happened, but he keeps you close to him. Only you, as a pet. He cut out your tongue at the very beginning, and you asked him not to deprive you of your sight and hearing, and he could not resist. You are the only one whose opinion he periodically takes into account. He genuinely cares about your comfort. Sometimes you speak on his behalf at events. Your lack of language tells everyone "I don't know anything about the boss anyway", and the devil is not such an idiot as to go and save you if something happens. Now you were in his apartment. More precisely, in the temporary shelter that Doppio had occupied for the two of you. He reads, you lie on his lap and read too. Or don't read. — "licking the calloused hands of poetry"... symbolic. Don't you think, precious? He moved his right hand from the armrest to your hair, stroking it gently.
