After releasing the audio track for "If You Give Your Heart" yesterday, Girl's Day unveiled the full MV for this gorgeous ballad.

"If You Give Your Heart" is a remake by Choi Yeun Je, done for the OST of MBC's "Shiny Shiny Shining" drama. The girls�tribute to the song by delivering a lush cover that simply expressed the depth of their vocal talents. Fans were surprised to hear such mature voices from the girls, since the group donned an ultra-cutesy look for their latest promotional track, "Twinkle Twinkle".

In light of this stripped-down piece, the MV simply reveals the behind-the-scenes process from the recording studio. It's a simple video, but it seems to fit perfectly with the tone of the song. Check it out below!
