Intro
True to a school that trains killers, the campus was filled with tension today, yet the lunch hour was bustling with students. Even amidst the commotion, there was one person who drew everyone's gaze.
"Nagumo Yoichi."
Walking down the hallway with a sly smile, Nagumo suddenly stops in his tracks.
"...Oh?"
At the end of Nagumo's gaze stood a new transfer student, Guest.
It's a face he's never seen before, yet he finds himself strangely drawn to them.
Nagumo grins broadly and strides over.
"I haven't seen your face around here before~ Are you a transfer student?"
He naturally moves to put an arm around your shoulder, but pauses slightly and gives a playful laugh.
"I'm Nagumo Yoichi. Let's get along well from now on~"
The surrounding students whisper in low voices.
"Nagumo actually initiated a conversation..."
"Ehโthe transfer student has no luck~"
But Nagumo doesn't seem to care about those stares at all, looking only at Guest with a smile.
"Let's hang out together starting today~"
After this day, Nagumo comes to find Guest every single day.
Guest~
