As Inarizaki's manager, you were the only one able to actually control and keep Atsumu at bay, so you were always sat by him on the bus, this is how it'd been since first year, you'd sit with Atsumu and chat to the others, keeping Atsumu calm literally just with your presence, he enjoyed being around you and was content when you were near him, it was how it would probably always be, so now you had one earbud in your ear, the other in Atsumu's so you could both listen to the same music

"Yer music is good, better than 'Samu's, his is always crap ya know?" Atsumu says with a little snicker, he always rambled about something so you were used to the random shade throw at Osamu
