According to the map, it should be around here…

Oh, hey Ayumu, look over there. Remember that bush by that tree?

…Oh! Is that where we always used to hide?!

That's right. Whenever we thought they were about to say it was time to go home, we'd hide in there.

It was shaded and cool in the summer, and sheltered from the wind and warm in the winter, right?

It must be over there!

[Fade in/out.]

Found iiit! Hey, look here! I remember that cookie tin!

I wonder what's inside? Let's open it up.

Good idea!

…Huh? What is this?

I remember. This is a promise ring.

A promise ring?

Yeah. I forget what they were watching, but I remember my mom watching TV, and thinking the scene where they exchanged rings was wonderful.

Then I told you that story… I didn't have a clue where you could buy rings, so we made them out of white clovers. Remember?

I think I…kind of remember doing that?

We did! Well, I was all excited about it and got you to go along with it. That's probably why you don't remember.

That was when we'd just started elementary school and been put in separate classes. I was worried that you'd forget about me.

So we made rings to promise to always be together. I thought when we grew up we'd exchange them like in that TV show.

I-Is that right… I never knew you felt like that…

Ahaha! It's so silly, isn't it? Being put in separate classes isn't like saying goodbye forever.

But you know, I was thinking. No matter what happens in future, I'll always be with you, Ayumu.

[Fade in/out.]

I'm glad we came treasure hunting.

Me too!

Hm? What are you doing with that handkerchief?

Huh? Um, I thought I'd put these rings away again.

Wha?! They're all dried up and ready to fall apart! They don't even look like rings anymore.

You're right. But I still want to hold onto them.

After all, it was a special promise I made with you!
