Kageyama and Hinata are walking to the gym because Kageyama left his water bottle there

"Hinata-chan...I'll go, get it, wait here..."

You saw Nishinoya and Tanaka

Tanaka: "HINATA-CHAAAN" Nishinoya: "SHOYOOOO"

But before Tanaka jumped on you your jealous best friend, kageyama gave them a death stare

Nishinoya: "BYEE" Tanaka: "BYE, SORRY FOR BOTHERING!!"

They ran away when you noticed that your friend felt very jealous
