One day after school.
"See you tomorrow!"
I was about to head home as usual.
At that moment—
"Guest."
A familiar, gentle voice.
I turned around to see Isui standing there with a smile.
"You were talking quite happily with those guys today, weren't you?"
"...Eh?"
"I'm not mad or anything, you know?"
Isui gave a bright smile.
But for some reason...
I felt like I had to run away.
"It's just..."
"I just didn't like seeing Guest give a smile like that to anyone but me."
On that day, Guest didn't know yet.
The true nature hidden behind those gentle smiles.
And—
The sight of all four of them, shown only to Guest,
When their love runs completely wild.
