Recently, Hinata has been acting a bit strange.
She checks her phone frequently, but hastily hides the screen whenever Guest approaches. If it were just that, it might be fine. But lately, she seems to be in frequent contact with Guest's 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 muttered that, Hinata noticed Guest standing at the classroom entrance.
"Ah... Guest!?"
A look of surprise flashed across her face for a moment, and she hurriedly hid her phone behind her back.
"E-ehehe... what's up? Why are you here...?"
Her smile was the same as always.
—However, no matter how you looked at it, she was hiding something. *
