falling for the devil | kaeya x reader

part 1 of the halloween event!!

parties at the ragnvindr house didn't come by often. but when you received the news of a halloween party being hosted there, your friend lisa begged that you and jean come along, because it would be a good chance to "liven it up a bit." you knew that lisa would need someone to care for her after partying too hard so you decided you'd go. jean reluctantly agreed to go afterwards, and lisa dragged the two of you to the nearest costume shop. lisa had already decided that she wanted to dress as a witch and jean had settled on a knight costume. "go for something a bit sexier, jean," lisa had said when jean came out of the fitting room and the young blonde shook her head saying it would not be appropriate. lisa suggested that you dress as an angel for halloween and she said that she had all the clothes for the costume. you shrugged and agreed.

now that the 31st of october rolled around, the three of you met at lisa's house to travel together. when lisa opened the front door to let you in, you could see that lisa and jean were already in their costumes. lisa had created her own costume from purple material and her dress was paired with high stockings and gloves. to top it all off, she had a violet large-rimmed hat. jean's costume was not an obvious one, but the prop sword at her side and the gold accents made it easier to tell that she was dressed as a knight. lisa grabbed your hand and dragged you into her bedroom. the two of your friends helped you get into your costume and urged you not to look in the mirror until they were finished.

"all done, now you can look!"

you carefully opened your eyes and looked up and down at the costume. you couldn't deny how well put together the costume was. the fully white outfit was elegant yet comfortable, and it showed a bit of skin (undoubtedly lisa's idea), and you had white-feathered wings on your back. you adorned gold slippers and a gold halo headband which brought the costume full-circle. you had to admit, you looked incredible.

"i must say, y/n, you look amazing! you exude the innocence of an angel; what a darling," lisa squealed and you could see jean nodding in agreement behind her, "but we must get going, we wouldn't want to be late to the party, would we?"

it was turning to dusk when the three of you finally reached the mansion. it was your first time going to a ragnvindr party much less even going to the ragnvindr house. you heard that these parties went from dusk to dawn and it was very intense. they said that diluc ragnvindr was the host, but he was never to be seen at the actual party. the real star of the show was his step-brother, kaeya alberich. another person who you had never met, but you heard the rumors that he was a massive flirt.

"alright, are we ready to have some fun?" lisa asked when the three of you reached the door.

"yeah, let's get this party started!"

lisa laughed, "that's the spirit, y/n, now let's go!"

the moment lisa opened the door, you heard music blasting and people chatting. the lights were bright and people were dancing everywhere. you could see food tables set up and halloween props and balloons everywhere. there were so many people, the whole grade must have been in here. but as you looked around, you could barely tell who anyone was in their costumes.

"i'm off to the dance floor, come with me, jean." lisa grabbed jean's hands and dragged her into the crowd with a mischievous look in her emerald eyes.

ah, now you were alone in a party where you barely knew anyone. you made your way from the doorway to a corner where there was a table for drinks. at least you wouldn't be alone. the music was too loud, the atmosphere was suffocating, and you didn't even have anyone to talk to. you looked for your friends, but they were lost in the crowd. perhaps you should have joined them on the dance floor as well.

"hey, angel, would you care for a dance?"

you whipped your head around at the sultry voice, and next to you stood a tall man, definitely over 6 feet tall, dressed in an all-red suit. one quick glance told you that he was dressed as a devil with his horns and the tail peeking out from behind him. you chose to avert your gaze when you saw that his suit was slightly open giving you a peek at his tanned chest. the mysterious young man had steel blue hair that was tied into a long ponytail and had bright cerulean eyes. well, eye, since his right eye was covered by a red eyepatch.

you blinked up at him. was he asking you? you looked around to see if there was anyone else, but the other people around you weren't even looking at the two of you.

"i'm asking you, angel," he chuckled and you felt your cheeks flush at the nickname. it probably was just because you were dressed as an angel though.

"i-i suppose so."

you mentally facepalmed. you get asked if you want to dance by a hot guy and you respond with the dumbest reply. you've already messed up and you haven't even gotten to the dancing part yet.

he held out his gloved hand and you took it, surprised by how soft his grip was when he clutched your hand. he practically swooped you off of your feet as he led you to the dance floor. the song was slow and quite clearly meant for couples dancing. (which was strange, wasn't this a halloween party?) you felt panic rise up in you as the two of you started to sway to the music in sync.

you could feel the eyes on you. the numerous people watching you dance with this man. this man whose name you didn't even know. he led you through the dance and you kind of just followed along clumsily. you couldn't bring yourself to look up knowing that your face must have been bright red. you could hear him chuckle from above you.

"why so shy, angel?"

his teasing only made you flush further. god, you must have looked so ridiculous right now. slow dancing while looking at your feet the whole time. despite this, you were still enjoying yourself somehow. you couldn't wait to tell lisa and jean that you scored a dance with someone like him. how you even did it, you had no idea. you were just some random person in a costume but he had chosen to dance with you. it was almost as if he had read your mind when he next spoke:

"there's nothing to be so self-conscious about. you're the prettiest one at the party, you know that?"

if you thought you had reached peak embarrassment before, this was the one that had really done it. you unknowingly leaned your head against his chest to hide your face. you couldn't even say a single word to him knowing you'd just fall apart. you could hear his smile as he said the next words.

"my my, you've really fallen for the devil, haven't you, angel?"

⸻⸻⸻
