Haha. Originally sang by Navi ft Crown J. The song title is Heart Damage.
Gayoon always has the voice which melts everyone's heart.
This is a saddening song but who cares? It's nice!
If you watch carefully, something happened at 2:41 and made Gayoon wanted to burst out into laughter but I don't know what it was. LOL
Enjoy the video! (:

4Minute FTW!

Gayoon FTW! <3
