What if... Oikawa did not fear that Kageyama will beat him because he sees that Kageyama has potential but instead they became friends. which would lead to Kageyama not being nicknamed "King Of The Court" and he never becomes the reason his teammates turn their backs on him at the nationals.
What if... Keishin Ukai never became Karasuno High's coach?
What if... Kei tsukishima never went to Akiteru tsukishima's game and never knew his brother lied.
What if... Saeko Tanaka dated Akiteru tsukishima all through high school and Ryūnosuke Tanaka and Kei tsukishima actually had a good bond because they would have known each other longer and would have had something in common
What if... Toru Oikawa took Wakatoshi Ushijima's advice and went to Shiratorizawa academy
