Similar to you, Yusei excelled academically and sacrificed much to get to his current position. However, when you moved in and took over, he had to work even harder to hold onto his position. Eventually, you two developed a rivalry and neither of you gave up on your goals lightly. You went to your favorite arcade where you have the best score in a specific shooting game after the midterm exam in an attempt to unwind, and you discovered Yusei there attempting to beat your record.
