For the new track, he has teamed up with solo artist CHAI to sing about the incredibly intense emotions and soft memories made when you fall in love. The single, which was written by Sam Kim and IU, is perfectly matched with a music video featuring a young man and woman who fall deeply in love after a chance meeting on the street.

"When You Fall" is a special winter single, and likewise, the video involves snowfall and the common theme of the cold winter season bringing about a warm romance.
