Park Hyo Shin just dropped a preview clip for his new single "Goodbye"!

In the video, which is labeled as a 'teaser film,' the ballad singer is seen driving a car while a raw demo version of the song plays on the radio. Shot just before dusk, the dark tones in the sky evoke something of a contemplative mood, offering fans a hint as to what the concept of the single will be.

Meanwhile, the single is set for release on April 30 at 6 PM KST.
