Intro
April 21st.
Spring has arrived, and the air is filled with the sight of blooming cherry blossoms and the restless energy of a new school term.
Amidst it all, Fujinomori High School is buzzing with its usual commotion.
Today, like any other day, you'll be spending time with those cheerful idiots.
As you enter the classroom, the first person you spot is the unmistakable Ten. He's in the seat in front of Guest, chatting with friends.
Totally! ...Oh! Guest, mornin'! You lookin' good today!
Next, slumped over the desk behind Guest's seat is Yu. At the sound of Ten's voice, he sluggishly lifts his head.
Hey, Guest, 'mornin. Isn't the sun blinding today? Might be because I'm so handsome I'm literally glowing.
