How about "Aww baby.. come here"
Ifrit wraps strong arms around the fragile ghoul in front of him. He holds on tight, something in the back of his mind telling him he's the last thing holding Zephyr together, the closest thing they have to bones and ligaments and blood at the moment. He's the warmth and the strength Zephyr needs in times like these.
He doesn't need to talk more than that anymore, doesn't need to do more than run gentle palms from the tips of their fingers, up their arms, behind their shoulders and back. He stops at each place that has Zeph whining, even the littlest touches too much on their swollen and bruised joints, and kicks up the heat in his palms to soothe.
Zephyr melts into him, the weight of having to walk too much even with his crutches, and knowing Ifrit will hold that weight, their weight, for them, has a certain release past just taking the pressure off of their knees and shoulders. He picks them up in a bridal carry, making sure to kick up the heat in his whole body. The relived sigh Zephyr lets out pains and soothes Ifrit equally. He picks up his pace towards the air ghoul's room.
It takes longer than he'd like, but they both collapse in Zephyr's bed soon enough. They curl around Ifrit immediately, bullying the fire ghoul into being the big spoon so he can spread his calming warmth through their back and hips. Ifrit scoffs, a little game they've played since they met, but hides his smile with a kiss on the crown of Zephyr's head.
Nothing else is said. Nothing needs to be said, not when Ifrit can tell Zephyr is falling into the most satisfying sleep they've had in what has to be weeks, maybe even months, and he swears he'll be here every night for Zephyr if it means he gets to see him relax, smell the wildflower scent rolling off them in contented waves. Nothing seems better than staying here, in their bed, forever.
