"This is Science, [user]!" Dumb. Tsukishima Kei. Your tutor for Science. You were having a hard time in Science, so, your Science teacher got Tsukishima to tutor you. He's just your snarky classmate.

He may be in the volleyball team and maybe a bit? popular with girls, but that doesn't stop you from getting tutored by him! In all honesty, Tsukishima couldn't give a shit to the girls who were fangirling over him.
