I notice that Taeyeon always closes her eyes when she sings ballad. She has her way, her own style as a singer. The magical thing I feel after hearing this is although Taeyeon didn't even look at Jonghyun for once while Jonghyun was always looking at her during the performance, I still can feel the song. I just can feel it. I don't know how to express this, just, they sang with their own heart, they gave their feeling into the song so maybe the performance was a bit weird (because there wasn't no eyes-contact between them), but I still can feel it. And one more thing, Jonghyun doesn't "struggle with" the song like someone said LOL :)) That's his style, always move his. Watch SHINee's performances or Weekly Idol then you will understand why. That's even one if his habit. :) - from a Shawol ♡
