Because the video includes songs from 2011-2013, "Mistake" was released before that Complete/Star Star Star for best slow SNSD songs!

Oh man, I cried my heart out watching the second season of Clannad. The song's great too.

Yuss, "Mistake" and it's written by Yuri That ballad comp would be really nice. Solo performances are good but I love the ballads with all the girls. Yoona may not be the strongest vocalist but her voice is so sweet :3
