Here you go! One fresh batch of fluff to sweeten your day. Enjoy!
---------------------------------------------------------

You knocked on the door to your best friend's house, or rather, apartment, and hoped she would answer. It's so late at night, but that's what makes it special. You called your bestie, Fionna, to ask her if she wanted to have a sleepover, and she excitedly said yes, you already planning the events in your mind.

"(Name)!" Fionna said excitedly as she opened the door. "Come in, come in, I have pizza."

"What toppings?"

"Normal cheese for me and (choice of toppings) for you, as usual."

"Gee, Fi, you know me so well," you noted, saying that last part in a mockingly elegant voice.

Fionna blushed at this comment and answered, "I'm your best friend! You're supposed to know the little things, right?"

You chuckled as you put on a scary movie for you two to watch. Whenever you hang out, you watch scary movies that are sufficiently scary, but also dumb, so you can make fun of them.

"Maaan, that one wasn't even scary at all!" Fionna commented.

"You were clinging onto me the whole time!" You retorted, to which she nervously chuckled.

Next was your favorite part: video games! You and Fionna love playing video games. You either play co-op games, which is most of the time, or you play something competitive, like Super Smash Bros.

"Hey, Fionna, I kinda need help over here!" You yell. You two were playing a co-op game.

"I can't," Fionna replies, biting into a slice of pizza. "I'm fighting a guy over here!"

And after the gaming was the most dangerous, rigorous, skill-challenging game anyone's ever made: Truth or Dare. You could either embarass yourself by doing something stupid because of a dare, or accidently spill out your deepest, darkest secret when you choose truth.

"Okay, so Truth or Dare?" Fionna asked, in an almost hushed voice, keeping an air of mystery about her.

"Hmm...truth." You locked in your answer, hoping you hadn't made the wrong choice. Alas, you had already sealed your fate.

"Is it true...that you have a crush on someone?"

You blushed. Where did this come from?

"Uh...I mean..."

"You said truth, so you have to spill the whole truth. Now, tell me!" Fionna exclaimed, leaning closer towards you and waiting with baited breath.

You sighed in defeat, knowing she would incessantly pry all night. "Yes, I do have a crush on someone."

"I knew it! Who is it?"

"How did you 'know it', exactly?"

"Well...to be honest, Marshall Lee and Gary had been hinting me about someone with a crush on me ever since I...you know...broke up with DJ Flame."

Darn those idiots! You couldn't believe that they had switched on you. Go be gay and get on with it, children.

"R-Really? That sounds like them..."

"Yeah. So, who is it?!"

You sat there and fiddled your fingers. You were quite nervous, but you believe that now is the right time.

"It's...it's you, Fionna. I...have a crush on you."

Fionna sat there, agape. She had a slight twinkle in her eye, as if of curiosity and intrigue.

"You do?"

"Yeah, I do. So...will you...dress up and travel with me?"

Fionna's expression changed to one of confusion. She deadpanned at you. "What?"

"Ugh, it's a– nevermind. I mean, would you like to go out with me? Like, date me."

"O-Oh! Uhm...of course! I actually wouldn't be opposed, hehe."

You hugged her as you smiled, feeling the happiest you've ever felt. She liked you back! Your crush liked you back!

Fionna reciprocated your hug and leaned her head into the crook of your neck. You could feel her mumble "you smell like flowers," which made you giggle.

When you two pulled away, Fionna was the first to speak.

"So, uh, now that the relationship is, like, official, do you want to, uhm, kiss now? Like, I UNDERSTAND IF YOU DON'T WANT TO, I just thought that...maybe we should kiss. But if you want to take it slow, I'll understand."

You smiled at how caring and understanding she was. "Yes, I would like a kiss."

And so, you two kissed, sparks basically flying as your lips touched. It was a pretty short and soft kiss, but you both enjoyed it nonetheless. You then continued the sleepover with pizza, arguing over a video game, and ending the night by sleeping together, Cake softly nestled between both of you.

P.S. Just here to say that whoever got the "dress up and travel" reference is a real one. 😊
