Crack written in a non-crackish way. It's my OTP behind Amorra but shouldn't be taken seriously.
He met her long before he met Avatar Korra, before Asumi, and long before he understood what love what supposed to feel like.
He knew what she felt like though: soft despite the years of hardship she endured, frayed around her edges like battle scars to be worn proudly. And wear her proudly he did; every damn day.
"Scarfy," Mako murmurs into her body, nuzzling into the warmth she provides. She could always be counted on for comfort and familiarity, and it's such a wonderful thought that Mako sinks deeper into her. Eventually he releases her from his face and holds her out in front of him to admire.
Gripping her by both ends, he entangles his neck with her so tightly that some would consider the act to be self-asphyxiation. But he simply needed to be close to her right now after the close encounter with a homeless man who accosted him in a darkened alley a few blocks away from the arena.
The man had made a grab for Scarfy, yanking her away from the security of Mako's neck before the firebender even realised it. The shock of having her out of his possession for even a second sent more chills down his spine than the frigidness of the air that now assaulted him without her to protect his neck.
So the man wanted Scarfy to keep warm at night, did he? Mako would keep him warm all right. Setting his hands ablaze, fuelled by fury of seeing her in another's arms, Mako had set the homeless man's clothes on fire and watched with sick satisfaction at seeing him struggle to remove the burning garments.
Of course he had directed the fire away from Scarfy and had quickly rescued her before any damage could befall her. He would never let another hurt her let alone hurt her himself. Still though, looking back on the encounter made Mako feel a little sick with guilt.
He felt like scratching Asumi's face off when she had made a move to remove Scarfy from his possession; he felt like ripping out Korra's hair and burning her mocha skin after seeing her adorn Scarfy like some damn accessory around her muscular neck, but he would never actually act upon those impulses.
Scarfy didn't mean enough to him that he would physically kill somebody for her, did she? Would he have murdered that homeless man in cold blood for his Scarfy?
Thinking back on all the meetings she's had with his friends and strangers Mako realised there wasn't a lot he wouldn't do to keep others away from her, and keep her in his embrace. It was a realisation that made him freeze and his stomach churn unpleasantly.
He would kill for her; he would kill for his Scarfy.
Unwrapping her from around his neck, he brought her to his nose, sniffing her cotton form and twirling his fingers around the loose ends. She was getting on in years, but she would always be beautiful to him. Even when her bright red colour faded, and when she no longer provided warmth, he would still love her.
Nobody could understand their relationship, Mako thought in despair. They already thought he was a little mad for the fact he wouldn't let them touch her. A quick sob-story regarding his deceased father stopped the questions though.
No, he and Scarfy would have to live their lives shrouded in secrecy, but it didn't matter to Mako. Nothing else mattered as long as he had her.
Firebending the currently unused fireplace in the room, Mako starts undressing completely, leaving Scarfy draped over a nearby wooden chair. By the time Mako had stripped to his underwear the room had reached a delicious temperature, providing the perfect amount of heat and light to be considered romantic.
He picked up Scarfy from the chair, and lied on his back close to the fireplace. Letting her form cover his bare navel Mako bundled one side of her and buried his face back into her. As he drew his leg up and around her in a comforting embrace Mako thought about the future, and how nothing or nobody could ever compare to such a wonderful lover, friend and companion as his Scarfy. Nobody.
End.
Sorry, not sorry. I highly recommend looking up Mako x Scarf on Google Images. Some of the pictures are hilarious. Also, please, please remember this as a real pairing if you ever r-ewatch Legend of Korra, everything becomes funny if you don't take it too seriously.
