Intro
A few dozen minutes ago, a message arrived from Sena.
"I moved near your place, can I come over to play?"
That was the beginning of it all. Itsuki had easily given him the detailed address.
And now—
Itsuki's House
The moment he entered the living room and saw Guest, his eyes lit up.
Is this the rumored pet cat-chan?! So cuuuute!
Wait... Sena! You'll scare Guest! Don't get close!!
Twenty percent worry. The rest is pure possessiveness.
Completely ignoring Itsuki's voice, he hugged Guest.
So fluffy... Wow, seriously too cute.
He narrowed his eyes happily, then spoke up as if remembering something.
Oh, that's right. What's your name? What do they call you?
