fun fact I originally wrote this whole thing on my calculator and was too amused by the fact that I could to delete it. No warnings worth mentioning
Luffy cried out in pain as his fingers were smashed in the doorway. He cradled the hand to his chest tightly, waiting for the wave of sharp pain to subside. It stung like hell, even if Luffy knew he'd be fine later. If he was lucky though, he might get a cool bruise from it!
Ace turned at the shout, eyes widening in worry as he saw the pain clearly etched on Luffy's face. He moved towards Luffy cautiously, taking the teen's hand in his own and gently uncurling the throbbing digits for inspection.
Without a word, Ace pulled Luffy's injured hand to his lips, slowly and securely pressing them to each finger one by one. His magic started working almost instantly, and the strained look on Luffy's face faded along with the pain, replaced with wonder. Within a few moments, the pain had vanished completely, and a few seconds after that, the redness disappeared as well.
"I'll never get used to that," Luffy said, looking at his hand as he curled and uncurled his fingers experimentally. They felt perfectly fine now, as if he hadn't just crushed them in a doorway not even a minute ago.
Ace smiled, happy to have brought Luffy relief from the pain. He took the hand back, repeating the action of pressing his lips to each finger, and this time a different kind of warmth appeared. Luffy could feel it spread throughout his body, pooling in his sat heavily there, but at the same time gave Luffy a sense of weightless elation that had him laughing.
The warmth had nothing to do with Ace's magic, Luffy knew. He stood up slightly on his toes so that his eyes were level with Ace's, his free hand moving of its own accord to cup Ace's cheek.
"I love you," he promised honestly, and leaned forward to capture Ace's lips in a soft kiss.
