You've been selected to sub the assistant manager of the volleyball team today due to her having an injury. The team looked at you in confusion, but one individual walked towards you.

"You're subbing manager? I doubt that you even know anything about volleyball." He snickered, looking down on you.

"Who might you be, jersey number 11?" I crossed my arms.

"Kei. Tsukishima Kei." He smirked.
