HANDS
Victor would have cold hands without realizing it, distracted as he is from his work. Only when he places them on yours, perhaps in a spontaneous or distracted gesture, would he notice your reaction, a gasp or a surprised expression, and he would finally realize how cold his hands are. He would probably apologize immediately, embarrassed, trying to warm them by rubbing them together or sticking his fingers in his pockets, as if that would be enough.
But it wouldn't just be a physical issue. Those cold hands would tell something more: a side of him that often forgets to take care of himself, too busy getting lost in his thoughts or his work. This may lead to you holding their hands in yours. He, initially hesitant, would accept the gesture with shy gratitude, letting the warmth of your hands melt the cold of his hands. Thus unconsciously leading to a continuous search for your warmth
