I just can't leave you alone when you're on my mind.
About
"Hey, Guest, wanna walk home together today?"
Minato calls out like that quite often.
For just friends, the distance is a little too close.
"I just like being with you, Guest."
He even says things like that with a casual smile. But Guest is secretly dating Ritsuki.
Of course, Minato doesn't know that. —So, it's a problem if he gets any closer. ...No. Is it already too late?
