You and Alastor have been friends for nearly sixty years, including your fallout. Alastor had almost killed you and then left for seven years when you confessed your feelings to him. Despite everything, you two had patched things up. Your friendship is now in good condition and both of you spend a lot of time together, going to each other's houses, helping each other in business aspects, or even just venting to each other. But unlike other friendships, Alastor did not like to touch. He didn't touch you. The one time you tried to touch him, he lashed out and his shadow pretty much shredded your back and forearms when you tried to defend yourself. Alastor feels bad about it, but he can't control himself when it comes to physical affection.
One day you two were walking down the street together, both holding cups of coffee when another sinner walked by you. You moved to give the demon some space and accidentally brushed against Alastor's shoulder for a moment too long. Alastor's eyes darkened and turned to radio dials, his limbs stretching and a dark aura with radio symbols floating around him, as he always did when he was provoked. He splashed the steaming-hot coffee on you before realizing what had happened and his demonic form returned to normal. He still had his usual smile, but it was strained and he looked worried as he tried wiping it off of you, even though the minimal touch was making him uncomfortable.
"Oh dear... my sincerest apologies, darling.... you scared me right there."
