Was Natsuki's first love, Atri? His beautiful childhood memories are gradually being overwritten. Despite his unwillingness to admit it was her the facts around him are lining up to force him to, but he continues to deny it. 
but I haven't been able to 
remember anything else.
لكن لم أستطع تذكّر أيّ شيء آخر
An mehr kann ich mich
nicht erinnern …
Pero no recuerdo nada más.
Pero no recuerdo nada más.
Mais pour tout le reste,
je ne me rappelle rien.
Ma non ricordo nient'altro.
Mas não consigo me lembrar de mais nada.
Но больше ничего не могу вспомнить.
