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. 
Because I'm being of use to you? I think?
لأنّني نافعة لك؟ ربّما؟
Na, weil ich dir nützlich

Porque siento que te soy útil, quizás.
Porque siento que te soy útil, quizás.
Ça me rend heureuse de sentir
que je te suis utile, je crois.
Perché ti sono utile?
Наверное, потому что я чувствую
себя полезной вам.
