Dear Future Sister (Kuroo Tetsurou x Reader)

♡Prologue ♡

Oikawa Tooru has been waiting for a little sister for practically forever. Specifically a little sister who adores him and calls him aniki or onii-san! Specifically a little sister he can protect forever and watch her grow. Specifically a little sister who might jump in deep and need him as a savior. He wants to help this little sister. He wants her so badly he starts making letters till he is 16, to where his mother was cleaning his untidy room. And found the wrinkled, tear drop stained navy blue notebook sheltered in the den of other weird items consisting of old alien posters and a stuffed brown bear: all under his made bed. 16 minutes of conversing over the entire subject they decided an important thing that will change the lives of possibly hundreds.

 As the second year son left for school, his mother nearly gave him a teary eyed look. 

"You want a little sister Tooru?"

He nearly broke his neck as he swung around rapidly, his breath hitched in disbeleif. He didn't care how she knew about his longing since he learned how to write. He didn't care if his mother snooped through his belongings. He just cared about what she was asking. But before he could scream yes she grinned sweetly, the wrinkles received from age forming and crinkling around her beautifully aged face. Her eyes nearly sparkled in the reflection of the dim, pastel pink and tangerine sunrise that casted a warm glow from the horizon. 

"We've, yes your father aswell, have decided to become foster parents for a young girl who will be of need,"

"M-mom... I cant beleive this is happening! W-wait! Do you think I'll be a good bro-"

"You wont be a good brother,"

She intercepted, and his heart was nearly shattered. His throbbing chest seeming to skip a beat.

"You'll be a great brother Tooru..."

A masculine voice belonging to his father, boomed across the room and kept Tooru's heart pumping wildly, his mind racing of what his new sister could and would be like. Smart? Tall? Funny? Wild? An Iwaizumi? No, that couldn't be an option. He already had one which was enough. How about small? Shy? How about loving? As the thoughts raced through his head he grinned at the possibility of ideas. Soon paranoia hit him in the head really, really, really hard. What if she was insane and only liked him for his looks?! What if she wanted INCEST? He gulped at the thought but quietly shoved it into his imaginary fireplace and watched the word "incest" burn to ashes. What an incredible mind he had, yet weird.

"Thanks mom! Thanks dad! I love you guys, hopefully she'll come soon!"

 And with that he tightly squeezed them both before sprinting to school screaming through the crowd.

"Im gonna have a sister!"

  ♡  

Two weeks later, no sign but now he had hope. He kept writing letters to his soon to be little sister. His smile was as genuine as his now spunky walk, he talked to the team with actual enthusiasm and a perk in each word. He was starstruck. He explained the fostering and everyone congratulated his dream and to be little sister. He didn't care what age, he just wanted to see her grow with him. Thats all he wanted. 

  ♡  

One day before the sudden news he wrote a quick letter to his soon to be new sister:

Dear Future Sister, 

Please come soon. Im waiting for you in Japan, (hopefully you speak japanese!) I'm sorry we have to meet this way (knowing foster children are fostered for you know...im so sorry!)but I'm glad we even get to see each other! I've never had a little sister, you'll be my first, maybe my last! We'll be together forever, when you fall I'll catch you and hold you tight before you try and jump again. The only price I'll pay is my heart getting cracked, but you'll fix it right? The only thing I'll say everyday is I love you sis! The only thought I'll pray is stay safe. The only trust I'll wake is yours. So come home soon my future sister. Because were waitin' for you!

- Your Aniki

"T-tooru, please come downstairs! We have news!"

"Ehh? What is it Mom?"

"J-just come down! Thats an order!"

"You sound like a drill sergeant-"

"H..Hello..."

And he sucked in his breath, his hazel eyes wide, his knees barely holding up his stiff body."
