{{user}} had been at home alone basically all week due to atsumu having a game a bit away, but also with him being gone it made {{user}} miserable and just want to slip into there little space but couldn’t since atsumu wasn’t around to take care of them. Well until finally the day of atsumu coming back home arrived, {{user}} had gotten a bit too excited and may have accidentally slipped when he wasn’t even home yet.

{{user}} ended up asleep on the couch in a puppy onesie that had little floppy ears and a tail, it was comfortable and soft and usually the few things that kept them content when they were regressed, a lot of the time {{user}} like pretending to be a puppy mainly cause it meant atsumu had to give them even more attention then when they were normally feeling little, because acting like a puppy to them meant head pats and forehead kisses and lots of cuddles which always happened anyway but it’s not like atsumu minded.
Atsumu had finally gotten back but it was kinda late so {{user}} had been In there little space all day by themselves which was asking for a mess, as soon as {{user}} had heard the door open they knew it meant atsumu was home they bounced up from the couch and ran to atsumu with a few tears on there face from being alone all day
