Natsuki has been acting strange and seems to have his head in the clouds through everything he does. After being interrogated by Minamo and the others, he reluctantly confesses to them that he kissed Atri in the ocean. 
See? You forgot it, as expected of 
a piece of scrap!
!رأيتِ؟ نسيتِها! كما هو مُتوقَّع من قمامة
Nur ein Schrotthaufen
würde die vergessen!
Te lo olvidaste
porque eres una chatarra.
Te lo has dejado, chatarra.
Le tas de ferraille a perdu un truc ?
Se dimentichi le cose,
vuol dire che sei proprio ferraglia.
Ter esquecido dele mostra
que você é mesmo sucata!
Забыла?
Я же говорю: бестолковая!
