Mitsuki and Nagi learn that Yamato has a secret based on his behavior at the party. Rather than being troubled by the secret itself, Nagi can't accept that Yamato is closing himself off from his friends. Yamato himself encounters his first acting wall at the filming location of his movie...
You can't stick with any one person, 
and nobody can stay with you forever.
لا يمكنك البقاء مع أي شخص، ولا أحد
يستطيع البقاء معك للأبد
Ihr könnt für niemanden anhalten
Incapables de se fixer dans la vie
et libres comme l’air.
Non riesci a restare accanto a qualcuno,
Você não fica com uma só pessoa e ninguém
consegue ficar com você para sempre.
Ты не держишься с кем-то ещё, и никто
не может остаться с тобой навсегда.
