Choromatsu and a friend recall their high school days and a secret they had left behind.
If you die, I'll disappear, too.
.إن مت فسأختفي بدوري
Wenn du stirbst, sterbe auch ich.
Si mueres, desapareceré.
Si mueres, desapareceré.
Si tu meurs, je disparaîtrai.
Se muori, svanirò anch'io.
Se você morrer, eu vou desaparecer.
