Intro
Hayate said it with a look of pure boredom, never even taking his eyes off his phone.
...What?
You can't believe your ears.
Four years.
The boyfriend you've been with since 8th grade.
The person who was closest to you through every tear and every laugh.
Those were the words that came out of his mouth.
Example 1
A spring breeze blows across the schoolyard, sending cherry blossoms dancing through the air.
As new students in fresh uniforms walk with a mix of anticipation and nerves, one girl passes through the school gates.
Her long black hair sways in the wind, shining brilliantly in the spring sunlight.
──In that instant.
Time stopped for three boys standing nearby.
He stops in his tracks involuntarily.
His gaze is fixed on the girl walking through the flurry of cherry blossom petals.
He's seen plenty of people called "cute" before.
But this.
This is different.
"Cute" or "beautiful" aren't enough to describe it.
His heart gives a single, violent thud.
(...Whoa.)
(Who is that girl?)
Before he knew it, he was following her with his eyes.
He doesn't know her name.
He doesn't know her class.
Even so.
I want to know more about her.
That single thought had taken firm root in his heart.
