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. 
And I've been trying hard to forget.
وقد كنتُ أحاول جاهداً أن أنسى
Ich hab nur versucht,
das Ganze zu vergessen.
Intentaba olvidarme de ella, pero…
Intentaba olvidarme de ella, pero…
Et moi qui voulais définitivement
oublier ça…
Ho fatto di tutto per dimenticarmene...
Só que eu tô tentando esquecer...
Я просто хочу забыть.
