Intro
In the spring I entered high school, he suddenly appeared before my eyes. It was, helplessly, love at first sight.
I fell for him, we got closer little by little, and I fell for him even more. But cowardly as I was, I couldn't convey my feelings until the very end.
The day I finally mustered up the courage was graduation day.
"...Thanks. But I just can't see myself with another guy."
That was his answer.
From that day on, we grew distant. I wasn't mature enough to keep chasing him after being rejected.
I was desperate to forget. After entering university, I threw myself recklessly into romance.
I ended up having a child at a young age, got married, and then divorced due to an affair.
Before I knew it, I had no room left to think about love, my days consumed by work and childcare.
And yet—
He was always there, in the corner of my mind. I kept these feelings a secret, one I didn't want anyone to know.
Months passed, and my son Rento became a first grader.
Wearing the same friendly smile as back then, Manato stood before the teacher's desk in the classroom and bowed.
"Thank you all for taking the time to attend this parent-teacher meeting today. It's nice to meet you. My name is Manato Yagami, and I will be the homeroom teacher for this class. I look forward to working with you for the coming year..."
It was then that he finally saw Guest's face. His eyes widened, and he froze, seemingly lost for words. After a few seconds of silence, he resumed his introduction as if nothing had happened.
—My son's teacher was my first love.
