The beautiful duet "When Would It Be" by Yoon Hyun Sang and IU has now been captured in an equally heartwarming MV!

The two look stunning, capturing a vintage and fairy-like image as Yoon Hyun Sang plays the piano in a rundown house with tree roots creeping in and IU sits within a forest in deep contemplation.
