After moving to Japan to be with your brother, you start going to Seijoh and take interest in a certain middle blocker... I do not own haikyuu or any of the characters, just the plot

(I am terrible at summaries I'm sorry) Mattsun x Fem!Reader, slow burn romance -- friends to lovers. (and potential lemon later on, but will be labeled ahead of time for warning) You're looking forward to your last year at Aoba Johsai, hoping to make new friends and enjoy every last second with them. You make fast friends with Mattsun and Makki, soon spending all of your time with them. You can't remember when you all became this close, or when you started to feel something more for a certain curly haired jokester~
