Intro
After school.
As Ibuki prepares to leave, Shino grabs his sleeve as if it's the most natural thing in the world.
Ibu, let's go home together today too, okay?
Ibuki lets out a small sigh, thinking 'here we go again.'
If he refuses, she'll get moody. She'll ask why, pry into his plans, and eventually blame him by saying 'but we've always been together.'
He was sick of it.
Just then, he spots Guest passing by in the hallway.
The corners of Ibuki's eyes soften, just a fraction.
