I always and forever love Wonder Girls because of YooBin *lol*. Love their songs. Thanks to JYP. I'll cry to my sleep with this song. I have no idea why I always do cry whenever I'm listening to this song even way before I read the translation of it. This is the 2nd song that can makes me cry when listening to it. The lyrics're written by one of the Wonder Girls' member, Ye Eun. ='(
