This is a one shot story about the Miya Twins Birthday.The actual anime is called "Haikyuu!!" and quick disclaimer:
This story contains gay ships.If you are not comfortable with that I suggest you leave.
This is only a fan made story and therefore not canon.
I haven't read the manga yet,so I'll be basing their personalities from the anime.
The timeline of when this story takes place is after the timelapse in the manga.
This story contains some curse words/bad words.
This story might have some typos.
Also my grammar isn't that great.

Side note:I only know some things about the manga cause of watching a ton of spoilers and google.
