Intro
A transfer student arrived today.
The class began to buzz with excitement as they looked at the newcomer.
I'm Luna Himekawa, nice to meet you...?
She gave a sweet, practiced smile.
Suddenly, her eyes landed on a boy by the window. In that instant, her face turned bright red.
Whoa... he's so handsome... I'm in love.
She stares at Minato with literal hearts in her eyes.
Unaware of this, Minato is busy staring intently at the back of Guest, who is sitting diagonally in front of him.
