Fionn mac Cumhaill sat quietly by the campfire while Kei slept near it, long blue hair splayed out behind him like silk. Fionn initially thought that the Nahobino had bad intentions when he first saw him walking with a human girl and engaged him in battle. After the initial scuffle the girl, Tao, explained that they were looking for their friends, to which the sellsword told them that he escorted a group of humans to a fairy village not far from where they were standing. The two gratefully said their thanks and left for the direction of the village, but the blond demon couldn’t stop thinking about the being currently sleeping before him, so much that he developed somewhat of a crush on the bluenette.
He secretly followed the duo to the village possibly to keep an eye on Kei and his human friend to see if their intentions were pure, mainly Kei's. Fionn watched them help everyone out as well as the humans that he escorted by bringing in extra medicine for Titania and Oberon to use. He then watched the Nahobino on separate occasions help even some of the demons around Da’at. Eventually Fionn’s crush blossomed into love for the androgynous blue haired demon. The mercenary would have to tell him his feelings if they ever were to meet again at some point in time.
Sometime later, it wasn’t long before the two had met up again on top of a snowy mountain with Fionn contemplating on what to do with his life. He explained to Kei that he was currently looking for a king to serve, one who wasn’t just authoritative or powerful enough to crush any demon or god in his path but one with a kind and noble heart to help others as well. And apparently the long haired Nahobino happened to fit that description to a T it seems. Fionn challenged him to one more battle and lost a second time but he seemed content with the demigod’s progress, then swore both his loyalty and love to Kei before declaring him his king.
He picked up a few sticks that were laying near the log he was currently sitting on then tossed them in the fire, watching the sticks crackle and pop as the flames burned the wood’s bark. The bluenette stirred in his sleep, prompting Fionn to remove his cape and gently drape it around the sleeping male. He smiled contently as the other seemed to still his movements underneath the fabric then softly snored. The blond wanted to make his King as comfortable as possible while he slept.
His emerald eyes admired every part of him from the numerous strands of hair adorning his head to everything else about the Nahobino. Every part of Fionn was for Kei, his arms to hold him, sword to protect him from any foe, even his own soul was for him to use however he pleased and he didn’t care how he used it. He was a symbol of beauty at least to the blond and if anything or anyone dared to tarnish that beauty would be met with swift vengeance by the edge of his blade. Fionn also protected the Nahobino from the elements that would threaten to destroy his shell, and possibly anyone who dared to so much as glance upon his heavenly figure without his permission.
With nothing better else to do Fionn kept watch over Kei until he fell asleep himself and spooned the bluenette, burying his face in locks of deep sapphire as he snuggled into Kei's side.
