“Kaeya Alberich, you know of the Cavalry Captain of the Knights of Favonius, do you not?”
“I’ve heard my fair share. He’s got himself quite a reputation.”
“I suppose that’ll suffice. That knight has been far too much of a hassle for us. He’s swift, agile with the way he handles things. He’ll use whatever means to get what he wants or needs so be cautious and rid of him in any way you wish. I trust you’ll be able to handle this so I’m counting on you.”
“Yes, as you wish.”

Tedious.
That was the best word to describe the situation you roped yourself into.
Kaeya Alberich, the esteemed Cavalry Captain of the Knights in Mondstadt was nothing short of a challenge. You were never one to question anything you were assigned to and you thought that this was gonna be some quick easy clean up but it was anything but that. You had to find a way to weave yourself into getting close to the said captain and by doing so, you had to play the long game. He was not a person that you wanted to underestimate by any means because the dwindling gossip you’ve heard about the man was nothing but the truth.
The moment you decided you would get involved with the man was the very moment the game between the two of you had begun. It was an unspoken exchange of moves that on the surface, was nothing but courteous and flirtatious remarks but in reality, these actions were laced with ulterior motives that each side hoped would bring them to be victorious in this little game. You weren’t a fool nor did you take him for one either. You knew that whatever you two had going had a darker side to the situation and yet, you decided to play along.
But it was getting exhausting. Although, perhaps that’s what he wanted.
To drain you, to get you in a vulnerable spot.
But you refused to let it get to that point.
And so you decided tonight was the night.

“They serve wonderful food as per usual. Never fails to disappoint me, truly.” You said as you opened the door to your place whilst you resided in Mondstadt.
“Of course, dear. I wouldn’t bring you to a place that was anything less than perfect. Only this best for you.” He smoothly said, speaking his part in the way he always does. So polished, so suave.
You simply chuckled at his response as you led the two of you inside.
“It’s not much but it does get the job done. Make yourself comfortable on the couch while I get you a drink, alright?”
“You flatter me too much. Don’t make me wait too long, though.” He playfully spoke.
He watched your figure disappear into the depths of your kitchen. His eyes began to trail around and scan around the room, observing the environment to the best of his ability. His hand traveled to the pocket at his side as he smirked to himself, simply awaiting for the events that the night holds to unfold before him.

You retreated into your kitchen as you retrieved the necessary materials to go about making Kaeya’s drink since according to you, this could be one of the last ones he might ever have. You popped open a fresh bottle of sparkling wine and poured it into the finest wine glass you had at the moment, three parts of crisp Dandelion Wine following right after, supplied from the famous Dawn Winery. You had gathered these fine wines specially for him, deciding it was appropriate to get the job done with ‘Death After Noon’, a concoction the blue-haired male fancied. You garnished it with small mint leaves as you pulled out the final ingredient for your mix.
You retrieved a small vile from your pocket that held a small amount of clear liquid. You dabbled in the art of alchemy in order to help you with the jobs you were assigned and in this case, it’d surely come in handy. You had prepared this poison just for this mission, making it so it wouldn’t kick in immediately but when it did, it would most definitely get the job done. You stirred the man’s drink together, making sure that everything was well mixed. You held the glass up, observing it thoroughly before heading back to where your target sat.
You walked up to him, holding the glass towards him, motioning him to take the drink.
“Death After Noon, huh? You know me too well, don’t you dear?” He smirked as he observed the drink filled glass he held between his fingers.
“Of course I do. Just a second I’ll be right ba--.” Before you could finish your sentence and take your leave, he grabbed your wrist, coercing you to stay.
“Won’t you come here and sit with me?” He asked, though it was a demand more than anything.
If you had decided to pull away and flee, it’d be far too obvious that there was something up and so, you decided to take a gamble on the situation and comply. He pulled you onto down, setting you on top of him, your legs straddling his lap as you faced him. The hand that held your wrist made its way to the small of you back as he held you firmly in place. You put both of your palms against his chest in an attempt to widen the distance between the two of you but to no avail.
Though the two of you had aimlessly flirted with each other, you had never found yourself this close to him. You got an up-close look at the captain as there was only so much distance between the two of you. Despite your duty in the situation, you couldn’t help but let a dusting of pink make an appearance on your cheeks. You had decided that faking up a shy, oblivious facade was the best way to go about in an attempt to drown out your suspicion.
“What do you have up your sleeve, Captain?” You called out to him by his title.
“I should be asking you the same thing, dear. Don’t play coy with me darling, we both know what’s going on here.” He spoke.
Your face dropped a little hearing his words, thinking that he may be quicker to catch onto things than you expected. Your eyes looked over to his drink that remained untouched as he continued to swirl the drink in his glass that he held between his fingertips.
“Is the drink not to your liking?” You asked in an attempt to change the subject.
He hummed as his attention diverted to the drink, observing it just as intently as the way you scanned it before you gave it to him. His eyes turned back to you, a dark look fogging over them.
“It seems you didn’t make a drink for yourself. I insist you have some of mine.” “Oh, but I made it for y--” You get cut off.
“I insist.” He firmly states.
You gulped, accepting your fate at hand.
“Now,” He started off.
The hand that was at the small of your back trailed its way up to the back of your neck, forming a firm hold on you once again. He brought you closer to him as he pressed the cold glass against your lips.
“Be good and open up wide for me.” He said as he titled your head back slightly, tipping the glass at an angle so that the liquid sin began to make its way into your mouth. You felt the cold mix make its way down your throat and you probably would’ve enjoyed the delectable drink if it weren’t lethal.
“You know, you’re quite the actor yourself, to which I will commend you for. You’re a quick one sweetheart, but I’m quicker.” He teased.
You were baffled beyond belief. You had planned and strategized to the point where you thought you were at least three steps ahead. In reality, wherever you were, Kaeya stood in front of you, taunting you from his spot.
“I was fully aware of the little game we had going on here. However, it was far too entertaining for me to want to stop. It’s like playing with fire, isn’t it?” He spoke.
He held a smug look on his face, one that simply mocked you. It was the face of someone who knew they claimed victory; victorious he was in this little game between the two of you. Your eyes begin to dart around as you begin to think of a way to make an escape. You could only hope that you would have enough time before your body decides to give out. Perhaps if you were lucky, you could even find an antidote. However, knowing your luck in the situation as of right now, you doubt Lady Luck would be on your side today. His grip at the back of your neck tightened and you flinched.
“Look at me.” He boomed with a demanding tone that he had never used with you until today.
He watched your throat move as you swallowed the liquid, scornful eyes burning with mockful vengeance as he reigned dominant in this situation. He was beyond ecstatic with the way the situation unfolded before him, the way you unfolded before him. He was able to turn the predator into the prey just by playing his cards right and oh how perfectly did he play them. The liquid slowly but surely disappeared as only a small bit remained in the glass-- and he was going to make you finish every last drop of it.
“That’s it, that’s good, love. Be a dear and take every last drop. We wouldn’t want this lovely drink to go to waste now, would we?” He spoke out, dumping the last of the contents into your mouth and setting the empty glass on the side table on the
“There you go. You were so good and you finished like I told you so. I could almost forgive you for poisoning me but unfortunately, I’m expecting a little more from you. Maybe if you continue to be good for me, I’ll consider forgiving you.” He smugly said.
The hand supporting your neck went back down to your waist as his other free hand made its way to your face. He wipes off the small amount of the liquid that dribbled down the side of your mouth. His thumb slides across your bottom lip, getting a feel for its softness before going in and indulging himself in your lips. He figured he didn’t even need alcohol to get drunk anymore, not when your lips made him feel tipsy as they were pressed against his own. Perhaps in your own way, you had trapped him with your own delectable taste that could rival his beloved Death After Noon; though he would never admit to it right now. He pulled away and looked you dead in the eyes as his one hand forced you to look at him.
“However, if you try and pull that stunt again, I’ll have you begging for me to just poison you instead.” He threatened.
His hand dropped from your face as it slipped into his pocket, grabbing something from inside. He pulled out a small little vile, similar to that of which carried toxic poison.
“You wouldn’t want this little game between us to end so soon, would you? Now, open up and take this antidote, sweetheart. The fun is just starting after all.”
A/N: First of all, all the inspiration and ideas are credited to chamberofsecretbooks on Tiktok. Saw the one video with this concept and I just HAD to write for Kaeya. I did make a few adjustments to it but all ideas stemmed from that one video lolol. Also, if you haven’t seen THE Kaeya video, please watch it. It is god tier. Anyways, Kaeya supremacy <3
