Haikyuu!! AU Week - Chapter 1 - ButterflyCrossing - Haikyuu!! [Archive of Our Own]
A Link to chapter 1 of my compilation of AU Week Fics. Chapter 1 is equivalent to Day 1, which is a Coffee Shop AU featuring the Kageyama Family Cafe and using the idea perpetuated by imaginethehaikyuukids that Kageyama has infinite siblings. Kageyama Akio belongs to ZodiacLeopard. The fic is also under the readmore.
