IRyS breaks into Kronii's house
Doesn't actually do anything to her
Just starts living there
Kronii is too scared to do anything about it
IRyS cooks food for the both of them and tidies up the house
Takes care of the animals
Casually sleeps on the sofa
Does all of this almost wordlessly
Kronii is terrified because she won't do anything actually terrible
Every time IRyS moves around the house or does something, Kronii gets scared and enters defense mode
IRyS just giggles and lets her be
Eventually becomes more relaxed around IRyS
Finally manages to sleep without locking the door to her own bedroom
Kronii wakes up with her ass feeling sore and with something wet dripping from it
IRyS is nowhere to be found
The entire house is clean and organized
Kronii looks around and finds a note
"Thanks for letting me live here for a while! You're so cute when you're scared, I couldn't resist descending inside you a little. P.S. you should lock your bedroom door"
Beside it is a cake with weird frosting
Kronii tearfully eats it
IRyS never shows up again
