Dean Winchester loves art, loves everything about it. Which is why he is covered in tattoos and does them for a living. But he also has other ink on him. Whenever he has a free moment he doodles on himself, but its not just for him. Its to hopefully bring a smile to his other half. Castiel Novak forgets, a lot. Which is why his arms and hands are usually covered in reminders for himself. He feels bad that all these little things show on someone else's skin, but he cant help it. But what he doesn't realize is that Dean thinks its adorable, all the little reminders like "set alarm", "pick up coffee" or " get more pens :)" that show up on his skin.
