Choromatsu and a friend recall their high school days and a secret they had left behind.
So that we don't forget this tragedy...
...كي لا ننسى هذه المأساة
Dass wir diese Tragödie
nicht vergessen.
Para no olvidar la tragedia.
Para no olvidar la tragedia.
Pour ne pas oublier
cette tragédie…
Per non dimenticare mai quella tragedia...
Para não esquecermos dessa tragédia...
