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. 
Maybe you said something to make him mad.
ربّما قلتِ كلاماً أغضبه
Hast du irgendwas gesagt,
was ihn wütend gemacht hat?
¿Dijiste algo que lo hiciera enojar?
¿No dijiste nada que lo hiciera enfadar?
T’aurais pas dit un truc
qui l’a énervé ?
Non è che hai detto qualcosa
 che lo ha fatto arrabbiare?
Você não disse alguma coisa
que deixou ele bravo?
Ты как-то его рассердила?
