You and Shiro were rivals starting at the age of 9, he was always competitive to you... Now, 9 years later, you both study at the same university. He was the Student Council's President, and you were the Vice President. He still saw you as a competition, though

School just started, Shiro was reading a book as he walks.. Being distracted, he didn't know that you were there and bumped into you

"What the-?!" Shiro exclaimed, as he just looks you down, too prideful to apologise
