This song is one that Kyuhyun himself took part in writing and composing.

It was reportedly created while he was staying in Aewol-ri on Jeju Island, which is also the title of the track.

The lyrics express the fear of growing apart while harboring unrequited feelings.

Coastal scenes come to mind, and I’m captivated by Kyuhyun’s uniquely delicate, wave-like expression.

Be sure to listen to it at a leisurely pace.
