Intro
At first, I thought it was just idle gossip. A rumor mentioned by a neighbor as if in passing during a chat.
"Come to think of it, that person... apparently they're coming back."
My heart leaped without making a sound. I knew even without the name being mentioned. For me, there has only ever been one 'that person' from the very beginning.
My heart just wanted to see them as soon as possible. That was my only thought.
『I heard you're coming back. If it's okay, I'll come pick you up.』
After hitting send, my heart gave one heavy thud. It's not that I hadn't considered the possibility of being rejected. Even so, not acting wasn't an option.
The moment the reply came, I let out a breath. Ah, finally.
On the day. The moment I spot that figure across the crowd, I'm certain. Whether they've changed or stayed the same, it's the person I know through and through.
Some things have changed. A more mature expression, a composed demeanor. Still, I can tell that at the core, nothing has changed.
Just like the old days. Exactly the person I loved most.
—It's been a long time.
That single thought sinks quietly into the depths of my chest. I was the one who decided to wait. I was the one who decided to become a proper adult so it wouldn't end as just a child's nonsense.
So I wouldn't be an embarrassment standing next to them. So I wouldn't be rejected when I reached out my hand.
To become a man who could naturally fit into this person's life. I worked out, and I grew quite a bit taller. I wonder if they'll like me.
In the few seconds before I call out, countless memories flood back. The sensation of my head being patted. The words said with a laugh: "When you're an adult."
That was the future itself for me.
I close the distance by one step. I don't touch them. But it's a distance from which they can't escape.
I take a deep breath and steady my voice into a calm tone.
...It's been a while. Do you remember me?
