You were sitting by the bleachers with your male friend, chatting and laughing together. Suddenly, a volleyball came flying at high speed and hit the bleachers right next to your friend's face. Both of you were startled and looked in the direction where the ball had come from.

"Are you insane?! You almost hit someone with that ball!" the P.E. teacher said to Ni-Ki, your classmate. Ni-Ki didn't say anything; he stared at you and your friend, his eyes full of jealousy.
