When innocent Jimin's mother asked him to take care of/"babysit" her friend's son for a while because of a business trip, he was expecting a toddler, not a 19 year old godly looking troublemaker on a motorcycle with tattoos and piercings (JiKook).
At first when I read this I was like “WUT, how am I going to do this? This was really interesting to write and I’ve never done this trope before so <3 @cutiepiebts did you say you loved Jikook babysitting au’s? :)
+ When Jimin’s mom asks him to babysit her friend’s son, he didn’t think much of it since he’s babysat for her friends before. Though, this was a newer friend.
+ He finds out that she will be away on a business trip for a week and her son, Jungkook, will need someone to stay with him. Jimin has handled toddlers before so he figures it will be easy money.
+ When Jimin arrives at the house, his mom’s friend explains. “Jungkook’s a sweet boy Jimin, he’s just a little…troubled. But I’m sure you two will get along.”
+ She calls him down the stairs and Jimin expects a toddler to come running down, not a grown ass man.
+ “Uhm, so where’s Jungkook?” He asks his mother’s friend. “Jimin, this is Jungkook.”
+ Jimin is awkwardly left in the hallway with his overnight bag and a smoking hot guy with piercings and tasteful tattoos.
+ “Just because you’re here doesn’t mean I have to listen to you. This ‘babysitting’ thing is a joke, got it?” Jimin isn’t amused.
+ The first thing Jungkook tries to do is sneak out to see his friends, and Jimin isn’t having it. “Where do you think you’re going?” “Out?” “Nice try, your mom said you can’t leave this entire week unless it’s with me.” “You’re not in charg—” “Do you want me to call her?” “…Fine.”
+ Jungkook doesn’t interact with Jimin much. He sticks to his room and glares at Jimin anytime he walks by to go to the kitchen.
+ Jimin catches Jungkook sneaking a couple bottles of liquor from the basement one day. “Uh uh, you’re mom said no alcohol.” “Oh come on—” “Jungkook.” Reluctantly, Jungkook puts them back.
+ Jimin can’t help but admire when the younger is wearing casual clothes like baggy sweatpants and plain t-shirts. It made him look softer rather than tough.
+ One day Jimin is trying to reach something from the top shelf in the kitchen. Jungkook walks by and plucks it from Jimin’s reaching hand before he can grab it. “You’re kind of short aren’t you?” “S-shut up you brat!”
+ Jimin notices that if they are in the same room, he can feel Jungkook staring at him in the corner of his eye and it makes him feel hot all over his body.
+ Jimin doesn’t particularly want to fight with Jungkook so he decides to cook him dinner with the supplies his mother left. He knocks on his door when it’s ready. “Jungkook, I made you dinner if you want some?” He gets no response. When the food gets cold, Jimin warms it back up and sets it on a plate in front of his door, and lets him know.
+ Jimin wakes up the next morning, stepping out of the guest room to see an empty plate outside of Jungkook’s door. This goes on for the next few nights. It becomes an unspoken ritual.
+ Jimin is sketching in the living room the one day when Jungkook finally emerges from his room and lingers around where Jimin is. “Thank you.” Jimin looks up in surprise. “For the meals I mean.” “Oh, you’re welcome Jungkook.”
+ Jungkook seems to take interest in his sketchpad and he finds out that Jungkook also likes to draw as well. “Maybe one day you can show me your work, Jungkook.” “Yeah. Maybe.”
+ Jimin gets a call in the middle of the night, only shaky breathing can be heard across the line. “J-Jimin, can you pick me up? I don’t know where I am or how to get home, I just—please.” “You left the house?” “A couple of my friends picked me up, I’m sorry.” Jimin grabs his keys and leaves the house without a moment of hesitation.
+ Jimin is able to pick up a shaken up Jungkook, and sits down with him on the couch, giving him water and a blanket to sober up. Jungkook ends up falling asleep on Jimin’s shoulder, and Jimin didn’t have the heart to wake him up.
+ The next morning Jimin wakes up to Jungkook startling and moving away. “Sorry…I didn’t mean to fall asleep on you.” “It’s okay Jungkook, I didn’t mind.” Jungkook is silent. “Thank you. For coming to get me. I don’t deserve your kindness. Jimin shakes his head and puts a hand on Jungkook’s face. “Don’t say that Jungkook. Of course you do. Stop thinking you’re a nuisance because you’re not. You’re important.”
+ Jungkook looks at Jimin with stars in his eyes, leaning in slowly with his mind blank, he kisses the older. And Jimin doesn’t stop him.
+ Jungkook’s mom comes back the next day. Thanking Jimin for his help, paying him, and sending him off. Jungkook was incredibly sad to see him leave, running out to Jimin’s car when his mother wasn’t looking and kissing him firmly. “Come back around. Okay?” Jimin smiles. “Only if you promise me a ride on your motorcycle.” Jungkook’s smiling eyes gleam. “Deal.”
+ Their mothers end up finding out a couple weeks later, but they were excited because Jimin had been nothing but a good influence on Jungkook. (Some would say they shipped it)
+ But Jungkook finally had a smile on his face, and that’s all that mattered really.
Bonus: Jimin did end up getting a ride on Jungkook’s motorcycle, and maybe something else :)
