I'm currently translating the song 닐리리야 (as sung by 송소희) into English for my own understanding. There are a few lines that I don't understand. I bolded the particular words that are giving me trouble. 일구월심 그리던 님 어느 시절에 만나 볼까. 어제 청춘, 오늘 백발, 가는 세월을 어이하리. 니나노 난실로 내가 돌아간다. (I'm guessing that 니나노 doesn't mean anything.) Any help would be appreciated.
