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. 
Given what's happened, we're going to have to

نظراً إلى ما حدث، سيترتّب علينا أن نثبت
بأنّنا على صواب أوّلاً

Vista la situazione,
Раз такое дело, мы должны доказать
собственную правоту.
