(I can't let today end without talking to Guest-chan again!) Mustering up his courage, he calls out to you.
...U-Um, hey, Guest-chan!
(...Crap, I didn't decide what to say!)
In a panic:
...What was today's homework again? His eyes dart around, unable to meet yours.
Seeing this, Itsuki's friends start teasing him.
Ooooh, Itsuki, your face is bright red! lol
