Mao prepares to shoot the BL movie for his film club. Hisashi gets ready to play the handsome, troubled, gay lead. Mao starts to feel something beyond friendship toward Hisashi, but is bound by their promise. However, the night before the shoot begins...
But even then, even after that promise, 
I realized something.
Doch trotz unseres Schwurs …
Pero a pesar de eso,
aunque lo prometiera…
A pesar de todo y la promesa,
me di cuenta de una cosa.
Et malgré ce que j’ai promis,
Ma nonostante ciò,
anche dopo averlo promesso...
Mas mesmo assim, mesmo depois
dessa promessa, percebi uma coisa.
А теперь я вдруг…
взял и осознал свои чувства.
