Giyuu spent the morning of school being bullied by shinobu but Tanjiro came to save the day. Giyuu's first class with with zenitsu aka the scared banana, Genya, and Tanjiro, so the class is good to Giyuu for the most part because it was math. The bane of Giyuu's existence, second to shinobu, but Tanjiro helps him out a lot, and Tanjiro for the most part, was the only one in the chat that had seen him smile, laugh and to be able to be himself. Tanjiro has Giyuu's best friend, same with Mitsuri and Kyojuro.
Giyuu snapped out of his thoughts as he heard an annoying voice "Tomkia-san! Are you there?", Giyuu's bane of his existence, Shinbou kocho. she was poking his back as he was working on his math homework and he struggling to keep his cool because he hated math so much that he would punch a child to be able to leave math class. Shinbou had her usual smile even though she was annoying the hell out of Giyuu. "what do you want Kocho." Giyuu said in his usual cold and monetone voice, Shinbou looked slightly sad at his cold voice but she kept smiling.
Shinobu then rambled about whatever was on her mind after she got his attention fully, Giyuu was drawing all over his math homework to just get away from thinking about math as he actually listened to shinobu for once in his life since knowing the sassy and small girl. Genya, of course, was blasting free bird on full volume without headphones on as he danced around the classroom because study hall had just begun but no one really actually studied expect Tanjiro, Zenitsu was sitting in the corner crying like he always was and Tanjiro was listening to smooth jazz as he studied hard for the upcoming test.
