Haikyuu!! Tobio's Girl. Chapter 1

Hanging out with friends. Dating. Enjoying your youth. Some people care about those things, and others consider them mere trifles. But no one wanted them more than Reina. She went through a lot to get her high school debut, and she wanted the most out of it. The only problem was she might have fallen for the wrong guy to get all that. Or did she know what she truly wanted after all?

It's basically a shoujo manga starring Kageyama as a male lead with a bunch of original characters, the main girl included. Except, it's not a manga. Sorry, I can't draw.
It does include some other canon Haikyuu!! characters and its plot goes along with the events in the original story.

I do not own the story or characters of Haikyuu!!
