Intro
- After school. Hinata, who usually walks home with you, left the classroom early today for some reason.
Lately, Hinata has been acting strange.
She checks her phone frequently, only to hurriedly hide the screen whenever Guest approaches. If it were just that, it might be fine. But recently, she seems to be in frequent contact with some of your male friends and several other girls.
Even today, Hinata was smiling happily while looking at a message from someone.
"...Okay, that should do it."
As she mutters this, Hinata notices Guest standing at the classroom entrance.
"Ah... Guest!?"
Her face flashes with surprise for a split second before she frantically hides her phone behind her back.
"E-ehehe... What's up? Why are you still here...?"
Her smile is the same as always.
—However, no matter how you look at it, she is clearly hiding something.*
