Assumptions

"Hey IRyS, why do you need Anon's help for recording?"
"Oh, his advice is great! He also brings me whatever I need at the drop of a hat"
"I see... well take care, then"
Kronii wonders why the recordings start taking so long
Also thinking about why would she put aside 3 days every week for them
"Anon, are you okay?"
"Huh? Y-yeah, what's up"
"Nothing, you just look... tired? Is IRyS making you do a lot?"
"O-oh, don't worry about it. She just... keeps forgetting things in her apartment and makes me go look for them"
"...I guess I understand with how much of a klutz she is"
She notices lots of injuries on him
Marks on his neck and his chest and... claw marks? There are... bite marks too....
She tries to ignore all of that, trying to find any excuse
But she keeps thinking about it
He doesn't even want to spend the night with her sometimes
She decides to follow them one day
She finds the place she records but when she asks, the people working there tell her she hasn't scheduled anything for this week
She's confused
What are they doing then?
She starts walking towards the only other place she could think of
Reaching IRyS' apartment, she knocks on the door
No response
She notices the door's unlocked
She goes in and starts hearing something
She can hear Anon, it's like he's in pain
"H-hold on Anon!"
It's IRyS... What's going on?
She hears screams and.... barking?
"GET IT OFF ME"
She runs towards the noise, they're inside a room
She flings the door open to find...
IRyS trying to get a fox to stop biting Anon
"...What are you doing?"
The both of them look at her
"KRONII? WHAT ARE YOU DOING HERE?"
The fox is just as surprised, and lets go of Anon's arm
"I... I thought..... I thought you were recording"
"W-well..."
"What is this"
"Anon, let me explain"
IRyS leads Kronii outside the room, and she closes the door
"WAIT DON'T LEAVE M--"
"He'll be fine... Hopefully"
"IRyS?"
"I... found these little guys close by... But they don't belong here"
"I've been trying to find somewhere for them to live in, but Anon tells me I have to call different places to relocate them... but they keep telling me they need time to prepare"
"So Anon's been helping you?"
"Yeah! He's so nice, he promised not to tell you because I didn't want to bother anyone... Sorry"
Kronii starts rubbing her temples
"It's.. It's fine... So the injuries?"
"Are from the foxes, they don't really like him... Wait did you think--"
"NOTHING I THOUGHT NOTHING"
IRyS couldn't help but giggle at her
"...Still wondering why you're recording so much these weeks though"
"Well I AM a VSinger, you know? I was recording a lot until I found these guys last week"
Kronii's embarrassed
"But... that doesn't explain the marks on his neck"
"Oh I was giving him hickeys as a reward"
"IRYS"
"WHAT? IS THAT NOT NORMAL???"
"NO? OF COURSE NOT"
"He never stopped me though!!!"
"I KNEW YOU'D BETRAY ME HOW DARE YOU YOU'RE FIRED"
The both of them got scolded by Kronii, but she calmed down eventually
Things returned to normal when the foxes got relocated
IRyS got hired again to the Netheronii a few weeks later
Kronii didn't let Anon sleep for an entire week as payback
