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. 
Huh? You're nicer today than 
you usually are, Natsuki.
ماذا؟ أنت ألطف ممّا أنت في العادة يا ناتسكي
Was? Du bist heute
viel netter als sonst.
Tu veux bien ?
Tu es très gentil, aujourd’hui.
Eh?
Ué... Hoje você está mais gentil
que de costume, Natsuki.
Что? Сегодня вы необычайно добрый, Нацки.
