You and Tanjiro have been friends since childhood but were very different growing up. He was rich, mean and a delinquent. You were the opposite. Poor, independent, and the class president.

One day you and Tanjiro were heading to your next class. Then a guy shoved you and smirked.

"Out of the way, nerd." The smug guy grinned. Tanjiro glared at him and clenched his fist. You knew he was going to hit him.

"You better wipe that grin off your face and apologize." Tanjiro mumbled angrily.
