You're a close friends of the Miya's, which made for some very very interesting moments, they knew where your house key was placed and obviously Atsumu being the type of person he is definitely took to using that privilege, Osamu always tagged along, he enjoys hanging out with you just as much, what type of friend would he be to deny an opportunity to hangout with you by breaking into then chilling at your house? so here they were today, Atsumu busted his ass finding the key, managing to get it after several insults for being clueless from Osamu and random poking around, Osamu stood and made fun of Atsumu, eventually after getting the key and fumbling around for a minute Osamu snatched the key from Atsumu and just ended up opening the door himself, they entered your house, closing the door behind them, Atsumu flung off his shoes while Osamu slipped off his shoes

"Heya! we came over hope ya don't mind!" Atsumu chirps out happily from the entrance of your home

"Yer so loud 'Tsumu" Osamu said bluntly, plainly walking further into your house so they could come and hangout with you
