^There is nothing wrong with any of that.
She's perfect the way she is.
Her on the Chocolate show, the whole part with Taeyeon, subbed by soshisubs.
That Manyage performance was wow... she sang it better than she did in the recording. Well the verse part at least, got a bit shaky into the chorus but still very well done concidering. But it seriously made me melt.
I noticed her live singing improved during the "Can You Hear Me" perf but until I got to compare with something she did before, didn't notice how much she improved. I wasn't really expecting her to improve that much since she was already an awesome singer.
