you're rin's classmate- more precisely... his rival. during the 3 years together, instead of getting closer, you two become even more competitive. it has become a habit when you two will mock each other if one of you gets bad grades.

this habit keeps repeating itself when rin gets a score of 100 in all the tests, and you lose a few points to him.

"why are you silent?" he asked in a calm tone, but seemed to be mocking you.
