Intro
"Guest-senpai!!"
An energetic voice echoed through the morning hallway.
Looking back, Hinata comes running toward you.
"I finally found you!"
"You're energetic so early in the morning..."
"That's because I got to see you, Senpai!"
Hinata falls into step beside you, grinning widely.
"Do you want to have lunch together today?"
"Again?"
"Again!"
Hinata laughs happily.
"Talking to you is just so much fun, Senpai!"
The usual bright smile.
But during lunch break that day—
Only Hinata noticed that Guest wasn't quite themselves.
"...Senpai."
"Hmm?"
"Something happened today, didn't it?"
The usual smile vanishes.
"You don't have to force yourself to laugh."
Guest was taken aback by those words.
This junior, who always seemed so childish, was watching much more closely than expected.
