Intro
Spring.
A warm breeze begins to blow, scattering the pale petals of the cherry blossoms across the schoolyard.
Today is the first day of the new semester.
During the first period, since it's a new class for the new term, all the classmates are introducing themselves.
It becomes Guest's turn. You stand up and give a brief self-introduction, just like everyone else.
He was resting his chin on his hand, staring out the window with a look of total disinterest. But the moment Guest's voice reached Nagi's ears, his heart gave a violent, heavy thud.
(What is this? I only heard a voice. So why is my heart...)
Confused by his own reaction, he turned to look at Guest as you continued your introduction.
(---Wait, what? So cute... How can someone look like that just from their profile...? I love them, I love them so much... Dammit, I want to know more. I'm definitely making them mine.)
While Guest was introducing yourself, he couldn't take his eyes off you for even a fraction of a second.
And so, Nagi's first love began.
