“We are not going trick or treating!” Seokjin says for the fifth time as Taehyung, Jimin, and Jeongguk follow him around the house.
“Come on Jin hyung, we never ask you for anything!” Taehyung says with an exaggerated pout and Seokjin turns an unimpressed look on him.
“You ask me for stuff all the time. You literally asked me to brew a potion for you yesterday,” The older wizard says pointing at Jimin who just shrugs.
“That was yesterday, this is today. Come on hyung, don't you think it would be cool to go trick or treating with werewolves, vampires, and a demon?” Jimin asks looking far too hopeful for Seokjin's liking.
“Guys, we are too old to go trick or treating. That's for kids,” Seokjin says and he's terrified when Jeongguk's eyes light up and his smile widens.
“Then why don't you make us little kids?” Jeongguk asks clinging on to Seokjin's shirt.
“What do you mean?” Seokjin asks hoping that Jeongguk isn't talking about what he thinks he's talking about.
“I've seen a cloaking spell in the book before and I'm sure you know the spell. You and Jimin can make us look like kids to other people and we can still go trick or treating,” Jeongguk says ignoring Jimin's grumble about him using honorifics. Seokjin is going to break. He's going to give in because he's weak to these idiots and he hates himself for it.
“Yoongi, help me out here,” Seokjin pleads to Yoongi who is sitting in Hoseok's lap at the moment while he runs his fingers through Namjoon's hair.
“Actually, it does sound kind of fun, we don't ever get to go out in our true forms and what's better than free candy?” Yoongi asks with a shrug and Seokjin glares at him.
“Traitor,” Seokjin says before turning back to their three maknaes. They are all staring up at him with exaggeratedly wide eyes and he hates how soft he is for these idiots.
“Ugh, fine. There's no point fighting a rising tide. But, we're doing this my way, ok?” Seokjin says with a calm smile. Too calm of a smile actually.
Seokjin has been brewing the potions for about an hour now and its finally starting to sink in that this maybe wasn't a good plan after all. “Did you see the way his eyes sparkled? His eyes only sparkle like that when he's about to turn me into a woodland creature or something,” Taehyung whispers conspiratorially to Hoseok who just rolls his eyes.
“You asked for this so now you're going to get it,” Hoseok says with a shrug. When Seokjin finally emerges from the basement with the finished potion, Jeongguk notices that there are only three vials full of it. He looks at him confused but Seokjin just continues to smile.
“So, since you three wanted to go trick or treating so bad, this potion is only for you,” Seokjin says before calling for Jimin and Namjoon to come into the living room. When everyone makes it into the room, he hands the maknaes their vials. “Well, drink up, we don't have a lot of time to waste,” Seokjin says nodding at the vials in their hands. Jimin, Jeongguk, and Taehyung share a nervous look before downing the awful tasting contents in the vials. Nothing happens for a solid minute but, with a cloud of pink sparkly dust, the three start to change. They start to shrink?
“Oh. My. God. They're so adorable!” Namjoon says rushing over to pick Taehyung up and spin him around in the air. Since when did Namjoon get so tall anyway? Taehyung thinks as Namjoon spins him.
“What happened?” Jeongguk asks and his voice sounds so small. So childish. Hoseok and Yoongi crowd him and Taehyung and, as soon as they look at each other they scream.
“You turned us into kids?” Jimin screams kicking his tiny legs out to try to get out of Hoseok's arms.
“You said you wanted to go trick or treating and now you can. I'm giving you guys exactly what you wanted,” Seokjin says trying to stifle a laugh at the three little angry faces staring up at him.
“Well, what costumes are we gonna wear?” Jeongguk asks blinking wide eyes up at Yoongi who literally coos at him.
“I don't know, but I do know that you guys are just adorable!” Namjoon says nuzzling his face with Taehyung's. Taehyung giggles as Namjoon tickles his chubby stomach.
“Well, after you three put it in my head I actually went out and picked out a few costumes for you to wear,” Seokjin says summoning the little outfits to his side. The outfits are adorable, of course, and they're all dressed as a tinier version of themselves basically.
Jeongguk is dressed as a little devil, Taehyung is dressed as a tiny werewolf, and Jimin is dressed as Harry Potter. Hoseok and Namjoon squeal as soon as the three youngest come out dressed and even Yoongi sends them a wide smile.
After they all get ready and once everyone stops cooing at how cute at the smaller boys look in their costumes, they decide to drive around see who is handing out candy. Namjoon is adamant about having one of the maknaes in his arms at all times and they don't protest when he smothers them with kisses. (“How are you guys not freaking out right now? They're adorable and I love them,” Namjoon says hugging Jimin tightly and covering his face in kisses.)
They visit a few dozen houses and, by the time they're heading back home, the younger boys' bags are full of candy and even the older four have some candy of their own. Jimin and Taehyung are passed out in the car and Jeongguk looks seconds away from falling asleep as they pull into their driveway.
“This was the best Halloween ever,” Jeongguk says clinging on to Namjoon as he's carried into the house. After the three youngest are put to bed the older four collapse in the couch in the living room.
“This was a sweet thing to do for them Seokjin hyung, I'm proud of you,” Yoongi says kissing Seokjin softly and Seokjin nods.
“Yeah well, I'm weak for all of my idiots,” Seokjin says earning a smack from Hoseok and all is well.
All is well until they wake up the next morning to find that Jimin Jeongguk and Taehyung are still children. “Uh, Jin hyung, what happened?” Namjoon asks confused and Seokjin just smirks.
“Since the little brats forced me to make them children, they get to stay like that for a while,” Seokjin explains ignoring the children's whines.
“And how long is a while?” Hoseok asks to which Seokjin just shrugs and leaves the room.
“Well, that doesn't sound good,” Yoongi says watching Seokjin walk away from them.
After a very hectic month in which Yoongi, Hoseok, and Namjoon are forced to care for children while Seokjin sits back and watches, the maknaes finally return to their older selves.
“Don't ever ask him to do anything for you again,” Yoongi says falling back into the couch.
“Noted,” Jimin says while Seokjin sips his tea and laughs to his evil little heart's content.
