Academic Rivals.

It sounds cheesy— but it wasnt far fetched in describing your relationship with Dazai.

Ever since you started highschool and bumped into him, it became a never-ending race between you and him on the topic of getting better grades, or seeing who studies less but gets a higher score on the random tests professors give out. Now, he was literally bragging about getting a single point more than you on one of your essay sheets.
