The world is a dark and tainted place.
Behind its beauty lurked dangers all around, ready to prey upon those who'd lowered their guards enough. Diluc is certainly no stranger to the horrors that hid itself from ordinary eyes, lying in wait for even just a single moment to strike.
He would wake up every single day with trepidation in his chest, constant vigilance being his way of life ever since the day he was awakened to the cruelty of this world. Any day could be his last and any moment could be his final one alive.
That is the reality he has come to grips with.
And yet, as you walk down the aisle with flowers in your ivory hair, so pure compared to his own flame-colored locks, you are a vision wrapped in lace as you neared him at the makeshift altar (hastily yet carefully prepared by his excited servants), Diluc found himself wondering if he was worthy of this happiness.
The Darknight Hero doesn't believe in fate. Not when fate showed him exactly what it intended to make of his life, one filled with eternal suffering and a never-ending thirst to rid the world of its evils.
He doesn't think much of the disoriented young lady he finds at the outskirts of Dawn Winery, wearing clothes that didn't seem to hail from any nation in Teyvat. But when he helps her up off the ground, he is met with a pair of innocent golden eyes and he feels something stir within the deepest recesses of his heart.
Though what it was, he didn't know at the time.
But now as he kisses you beneath the foot of the statue of Barbatos near Dawn Winery, the scion of the Ragnvindr family knows that despite the darkness and dangers that lurked about, there is still hope. Suffering and sadness existed so that humanity can know what happiness and love are.
And by the archons, he never knew what true happiness was until he'd whisked you off to your new shared chambers within the manor. He knew no other anxiety than that of the uncertainty of tomorrow, but even he couldn't help but swallow the lump that formed in his throat when you fully bared your body to him for the first time.
"You're beautiful," he murmurs, reverently caressing each dip and curve in your body with soft yet firm hands before latching his mouth on whatever patch of skin caught his eye, nibbling and sucking until it turned a pretty pink color. "So sweet and so soft...I could eat you right up."
And eat you up he did.
The ginger painted your skin with bruises and lovebites, a canvas for his wandering mouth and hands. He made sure that the ones on his favorite spots would take the longest to fade, unabashedly wanting his claim over you to be obvious that only a blind man can't see that you were utterly his.
"You're already this excited from my mouth and hands alone? Forgive me for neglecting your most precious place then, my darling. For my negligence, I will make sure to compensate you handsomely."
You are practically sobbing when Diluc finally relents in his assault and pulls away from you with a final obscene slurp. You could barely look at him straight as he licks off the clear viscous fluid that stained the corner of his lips all the while staring at you with clear desperation and want.
"You taste exquisite, my love. However, I believe it is about time we begin the main act. Shall we?"
And so, the rest of the night was filled with debauched screams, moans, and whimpers of pleasure as your new husband made love to you until daylight peeked out of the darkness. If you hadn't been draconic in nature you'd have probably passed out by the 2nd hour, but thanks to your other-wordly stamina the two of you kept each other up without trouble.
Thanks to that, it wasn't any surprise that 9 months after your wedding night, the residents of Dawn Winery welcomed their newest young master.
Diluc sat at your bedside after you and your son had been cleaned and wrapped in new clothes. His eyes never leave you both as you fed your son his first ever meal, marvelling at the sight of this little creature that both of you created together out of love.
"What shall we name him, my love?"
"I like the name Aurick...Aurick Daemon Ragnvindr"
"A splendid name it is"
Diluc smiles and repeats the name softly under his breath.
The taste of bliss has never been sweeter than where he is right now.
