Muhyo, Roji, and Nana visit a rustic hot spring resort to meet a client. They bathe in the hot springs while waiting for him... and then Roji catches a middle-aged man peeping into the women's bath at Nana. The man turns out to be their client and the author of a current best-selling novel series, "The Butterfly of the Night," Yontani Abeyuki.
so I was just clinging to 
The Butterfly of the Night.
لذا كنتُ متشبّثاً بـ "فراشة الليل" وحسب

den „Nachtschmetterling“.
Así que me aferraba

Así que me aferraba
a Mariposa de la noche.
Je me suis cramponné
au Papillon de nuit !
Per questo mi sono aggrappato a 
La farfalla della notte.
Então eu estava me prendendo
à Borboleta da Noite.
И потому цеплялся за «Ночную бабочку»!
