Where was the maid, indeed?
Normally, Ushio was very prompt on arriving after class. After all, she wasn't brave enough to hang around and risk her classmates striking conversation. That would be far too embarrassing and terrifying! However, as Ushio didn't want to constantly flee from her own classmates for little reason beyond 'kyaaaah too awkward', the pink-haired young lady decided to try something shocking and bold! ...Well, for her standards, at least.
Unfortunately, this had left her trapped in the bathroom for a while.
She had wanted to get changed as soon as possible, so changing her clothes in one of the stalls seemed like a quick enough destination to do so. Unfortunately, halfway through putting on the maid uniform she would wear for her friend, other students had entered the bathroom, loudly chatting to each other about trivial things. And simply did not stop.
What little courage Ushio had mustered towards wearing the maid uniform in public quickly eroded as she waited, completely still, for these students to leave. When they finally did, the trembling girl had slowly put her school uniform back on, maid outfit folded and replaced into her bag.
And now, nervously poking her head into the classroom that Hiromi was waiting inside of. There was hardly anyone else around, which was nice, but... she was so late now! The two girls had been around each other long enough that Ushio wasn't expecting to be yelled at, but...
Still trembling, the blushing girl slowly entered the classroom and stepped towards her employer/friend, stopping a few feet away and quietly murmuring her presence.
"S-sorry I'm la-late... um..."
Stating the reason for her tardiness was proving too embarrassing to do, and her explanation died immediately, Ushio watching the bigger girl bashfully.
