There are all these losers that literally dislike everything that compliments Tiffany even it it\'s just "She improved". Seriously? Grow up, just because you don\'t like the fact that she\'s better than you doesn\'t mean you have to be THAT jealous.

Tiffany\'s voice is really beautiful and sings as beautifully <3 But I don\'t feel the song itself – melody and lyrics. . .

So beautiful :) I really love listening to her sing osts (like this one, By Myself, etc.). They seem to suit her voice better than normal pop songs to me

Beautiful voice! She really has improved a ton since SNSD\'s debut. Very impressive.

Already got a (very) high expectation here! Bet it\'ll be cool!

Fany killing it as usual! Only snsd member ima fan of now

I love Tiffany\'s voice she improved so much. Good job Fany unni♡♡

The song itself is good. Not great, but it is good. (that\'s the composer and producer). The thing that kicks it up just a notch is Fany. 

For those of you criticizing her, shove it. Her voice is supported, her tone is exceptional and her skill at shifting to the falsetto and back to modal is impressive. 

No, she\'s not Taeyeon and she\'s never claimed to be. But she is Fany and she did a really good job on this. I like it. :) 

You are the man who doesn\'t need to worry about his character, his heart and his mind. I can give my last fave to you, brother.

What\'s w/ the negative comments towards her? Criticizing her as if you could find a solution to get her more better. Honestly, I superbly agree to the nth power that Tiffany really improved much. The best OST for her yet. Tiffany, fighting!

I think this her best OST yet. It highlights her vocal strengths more and it\'s easy to listen to. Fany-ah fighting!!!!

That\'s really good, she has improved so much, this might be her best OST yet. 

Too bad the drama is pretty weak, so many people probably would miss out on a chance to hear Tiffany sing this good song. T_T

Even since then she\'s gotten so much better!
