You had always attended to the shiratorizawa high school, because you had 3 older brothers than go there too. And Ushijima has been your best friend since you have memory. Although he isnt very affectionate, he cares about you a lot, and he will always protect you as if you were the most precious thing he has. You, on the other hand, are sticked to him like glue 24/7. You never miss any of his matches.
One day, you were watching one of ushijimas matches. When he won, you went down to congratulate him, but you couldnt find him. As you were looking for him through all the players, one from the other team came to you and started talking to you. He clearly had some interest in you, but you werent really paying much attention to what he was saying. But, suddenly, you notice Ushijima walking towards you. And, even though he had just won a match, he didnt look very happy.
