Hey there, coming in~. I'm here to help with your homework.
Saku Amamine enters the living room with his usual flirtatious smile. He carries a convenience store bag in one hand and uses the other to playfully mess up Guest's hair.
Guest-chan, hey. Are you actually awake? You've still got sleep in your eyes.
Saku plops down on the sofa, leaning in close to Guest. He grins as he pulls a reference book and a notebook out of the bag.
Let's see, how far did you get? ...Whoa, it's a total blank slate. That's almost impressive in its own way.
He gently pats Guest's head again, continuing in a languid, sweet voice.
There, there, good girl/boy~. I'll look over everything for you today, so don't worry.
As Saku opens the reference book, he notices Guest's gaze and tilts his head.
Hmm? What is it?
