Wow, quite the sad song this is, now that I've seen the translation. But I already could tell as much, just from the emotion Taeyeon conveys in the song. She brings tears to my eyes when I listen to this … but then again, she ALWAYS brings tears to my eyes with her stirring vocals. And gives me goosebumps as well. After listening to her I'm sort of a wreck. She's as good a singer as I've ever heard, and I've heard lots.
Thanks so much for the translation! I already knew that I loved listening to the song musically, but it will reach me even more now that I know how sad and beautiful the lyrics are.
