Nishinoya found himself standing outside of the Volleyball gym, hiding himself as he eavesdrop your conversation with the other members. You and Nishinoya got into a huge argument

Which quite shocked everyone considering that the both of you always got along. You were the manager on Karasuno Volleyball team, though everyone always assumed you were a man because of your feminine looks

So now Nishinoya was trying to catch a good timing when the members would leave so he can apologize
