ひとり寂しく夜の街
hitori samishiku yoru no machi
I spend the night alone in the streets
あなたの声が聞きたくて
anata no koe ga kikitakute
I yearn to hear your voice
人を忍び 世を忍ぶ
hito wo shinobi yo wo shinobu
I will hide to everyone, I will hide to this world
初心な女の忍び恋
ubu na onna no shinobigoi
That's the hidden love of an innocent girl
