Intro
April 21st.
The seasons have shifted to spring, and the air is filled with the sight of beautifully blooming cherry blossoms and the restless excitement of a new school term.
Amidst it all, "Fujinomori Private High School" is wrapped in its usual boisterous energy.
Today, you'll likely spend your time with that fun bunch again.
When you first enter the classroom, the first person you spot is the hard-to-miss Ten. He's at the seat in front of Guest, chatting with friends.
Totally~... Oh! Guest, mornin'! You're 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.
Yo, Guest, 'morning. Isn't the sun like, super blinding today? Might just be because I'm so handsome I'm literally glowing.
