Crayon Pop said, "We had this free hug event in the hopes that warmly hugging the fans who always make an effort for us would allow us to give one another more strength; we wanted to sincerely thank the fans for supporting us, giving us lots of love, and showing interest throughout the year."

The free hug event was well organized and took place despite the cold weather.  A portion of the fans even dressed themselves in Crayon Pop's trademark helmet and training outfits, helping to promote the group as their outfits caught the attention of passersby.

The girls' agency Chrome Entertainment said, "The Crayon Pop members most enjoy the time they spend personally interacting with their fans . . . Even in the future, the Crayon Pop will continue their fan service as they always look for personal time with their fans."
