(the images become more out of context and more unrelated to the fanfic when I write lmao also your little bro will be bf/keith and you are yourself. Not hatsune miku 😌)

The clock on the wall in the living room ticks loudly as you sit patiently on the couch, waiting for a certain babysitter to pop in front of you. You bounce your leg, continuing to watch the time go by, hoping he'd arrive soon enough. Your little brother, Keith, was having trouble sleeping again and you knew exactly the guy that could help as always. You furrow your eyebrows in nervousness as the clocks ticking becomes louder and Keith grows more rambunctious.

You immediately sighed and got up, thinking Boy wasn't going to arrive tonight, but before you could grab Keith and take him upstairs a familiar voice made you stop in your tracks. "Where ya goin, pal?" You spun around so fast that you almost fell. You looked at Boy who looked right back at you with a big goofy smile . Keith jumped out of your arms and ran up to him and jumped up on Boy's bicep, laughing as Boy let him dangle off of it. He chuckled and you walked up to Boy.

He quickly averted his attention from Keith and set him down on the ground gently. "Hi Boy! I-whoa!" You squeaked when Boy picked you up and spun you around, laughing loudly. "Its great to see you again, Lil Y/N!" He called you Lil Y/n because you were well, shorter than him. You laughed as he continued to spin you around, before he set you down on the couch. You put your palm to your forehead and groaned lowly. "You don't gotta always spin me around when you see me, heh-" You rubbed your forehead as Boy grinned.

"I can't help it. Not my fault you're super light and short and fun to pick up." He boops your nose and you snicker, swatting his hand away. He turned his attention back to Keith who was sitting on the floor, pouting. Boy walked over to him and picked him up. "Come on, bud. Let's go upstairs and have some fun!" Keith clapped his hands in excitement. He loved it when Boy sung with him or did anything with him for that matter. Sometimes Girl was around with Boy as a duo and you enjoyed her company as well, but it was only Boy tonight and that was a good thing.

You smiled as Boy took a giggling Keith upstairs to put him to sleep like a good babysitter. Once they were fully out of sight, you decided to grab some snacks and watch TV while time passed by. As you sat back on the couch and turned on the TV, you think about how long Boy has been with you and Keith. He's been helping you take care of Keith for almost a year and a half now. He was an extra set of hands you didn't have, but always needed when it came to Keith.

Boy wasn't always around at night, because he of course has to babysit other children, so you would be stuck with trying to get Keith to sleep. It was always difficult at first, but became easier over time. Still doesn't mean you don't have a hard time trying to drag him upstairs to bed. Boy honestly treated Keith like his own son and it made you relieved and happy to see Keith bonding with Boy like he was his own father. You were technically the adult in the house after your parents left for unknown reasons. It still makes you think about where your parents ended up going once you reached the ripe, responsible age of 18.

They were either dead or alive and thinking about them not being here anymore made you deeply upset, so you had to focus your mind on something else. Boy and Keith could be visibly heard singing upstairs. Sure it was loud and probably a disturbance to the neighbors, but you knew it was a good way to get Keith to sleep. You smiled and looked down at your hands and interwined them. You began to think about the relationship you and Boy have together as caretakers.

Boy definitely saw you as a great big sister to Keith and knew exactly how hard you worked just to keep Keith fed, clothed and sheltered. To be honest you and Boy were almost close in a way like you two were married. It was funny to think about, but Girl tended to tease you both about it when she was around. You and Boy laughed it off, but was it really a joke? You weren't sure sometimes. He honestly really treated you like a wife. The way he talked to you in such a lovingly and joyous tone. He enjoyed hugs and laying with you on the couch watching TV. He accidentally called Keith son on a few occasions which you found funny, but sometimes he almost slipped up and called you "honey" or "his wife", which he claimed was a joke.
