If people come up to you and your brothers, they would often ask :

"Aw, what a cute child! Who's does it belong to?"

Well, surprise surprise. They would be shocked and probably wouldn't believe if the answer is....

"Oh, she's my little sister and we're her big brothers"

Since you and your six older brothers have a VERY big age gap between you guys, people would often mistake you as one of their children. But in reality you were their younger sister.

Your Mom and Dad were tired and bored from handling six grown men, so they decided to adopt a daughter to spice things up. You were three months old when you were adopted which means your brothers were 21. At first they were shocked, infuriated, and dumbfounded that their parents adopted a literal child without them knowing.

But after years of raising dear (Y/N), they all became attached and obsessed with her, maybe even a bit overprotective. She was the cute little bear in the family, she wouldn't talk that much and would get shy pretty easily which the whole family thinks is adorable.

What (Y/N) LOVES to do however, is to play Hide And Seek! She loves that game so much that there wasn't a day where she didn't play that game with the Matsuno brothers and her parents.

One unusual day, (Y/N) was sitting by the  Akatsuka table drinking choclate milk. One of his brothers came in the room and sat beside her while ruffling up her hair.

"You've been drinking a lot of choclate milk this morning, do you ever get bored?"
He asked with a slight comforting smile, you turn your head around and see Choromatsu smiling down at you.

"Never! I love choclate milk, wanna try some Nii san?" You handed him the glass of choclate milk, he seemed surprised a bit.
"O-oh! Heh, it's okay (Y\N). You can have the chocolate milk" He says before giving it back to you, you shrugged and continued drinking. Choromatsu didn't leave apparently and it looked like he wanted to tell you something.

"So, ahem, (Y/N)....I want to tell you a BIG secret okay? You canNOT tell anyone in the family about this" He says in a playful way, you started getting excited on this secret of his.

"Ooo! What is it Choromatsu nii san?! Tell me! Tell me!" You said with a big smile, Choromatsu sighs sadly and patted your shoulders.

"Guess what? I finally found a job I can apply to!" He says with a smile, your eyes started to sparkle with excitment and you lunged yourself to your Nii san.

"Woohooo! Choromatsu nii san found a job!" You hugged him, Choromatsu chuckles but something seems a bit off. He may be smilling but his eyes says otherwise.

"But, I have to leave for a few months before I can come home.....it's part of the job.....is that okay with you?" He tilted his head, you don't really understand since you were only seven so you just nodded.

"Heh, glad to hear that. Remember~ keep this a secret! I'll tell everyone tomorrow night if that sounds good" He says before playing with your strands of hair. You chuckled and nodded again before you two hugged

It was the late afternoon, you were in the bedroom chilling with Totty, Ichimatsu and Jyushimatsu. Boredness came rushing through your body as you roll over on the futon. That's when you started thinking of playing yet another game of Hide and Seek!
