What Park Jimin want in his life is just a simple part time job so that he can buy the newest version of his limited edition figure Anpanman. And when he got a call from his bestfriend Min Yoongi, asking him to babysit his niece, he was more that willing to help as that man offer him a fortune that he can even buy the new pair of gucci sneakers with the extra money. Well 6 months is not that long and he just need to take care a kid, he even love kids so why not? But then, when he open the front door of his apartment, expecting a young kid to jump up and down infront of him, he see another else. And thats when he know he'd fucked up. "The heck yoongi! She's not a kid?!" "Since when that I said she's a kid?" "Are you kidding me?! She's an adult!" "Pfft, she just 22, she still young." "And I'm 24!" "Good then, she still younger than you." Yeah, 6 months is not that long and he's taking care of 22 years old kid, so everything's going to be alright. Right?
