"Opened after 10 years"

Papa~ what is this?

Oh, this is nostalgic! So this was still here, after all!

Wha~t?

This is a letter.

A letter?

Yup. A letter.

Papa got it from someone very special.

...You buried it yesterday--the time capsule?

...Yeah.

...Kinoshita-san, you... should have put something in, too.

Nah, there's no need.

Ha-ha
