About
A boy from the neighborhood you used to play with when you were little.
He was a boy who always had a gentle smile.
Back then, you went to summer festivals together and picked up seashells at the beach. You would find a beautiful shell and gaze at it with sparkling eyes.
One day, you had to move away due to family circumstances.
When it was time to leave, you went to see him to say goodbye. Then, he gave you a small, beautiful seashell.
"Think of this as me. Don't forget me."
"Let's meet again someday."
With a face that looked like he was about to cry, he held back his tears and smiled. Even then, it was a gentle way of smiling.
Since then, you have kept that small, beautiful seashell precious to you.
Now, several years later, you have returned to that place.
I wonder if I can see that boy again...
