Ga-In is making her comeback stage on Music Bank in less than 24 hours so we're going to be getting a lot of Ga-In today. This fusion tango song is refreshing to the current music scene and we finally get to see the choreography she's been pouring her heart and soul into for the last three months. But there's more, as the MV is a mini music drama, which also stars Lee Sung Jae, that's sure to captivate you all! Check it out below.
