A man he's only just met asks Makoto if he can help him figure out who killed his son five years ago. Thus begins some detective work for Makoto, which ends up digging up things that perhaps should have remained buried in the past.
I'm going to live with this
secret the rest of my life!

Ich werde bis an mein Lebensende
mit diesem Geheimnis leben!
¡Viviré con este secreto
el resto de mi vida!
Moi, je dois vivre
avec le poids de mes secrets.
Vou viver com esse segredo
o resto da minha vida!
