Director Hur Jin Ho commented, "We filmed 6 episodes in about a week and it was really fun working with great actors on set."

Actress Han Ji Min mentioned, "I decided to take part in this project because I thought it would be a good chance for me to present light to those suffering from vision impairment. The episodes were based on actual stories of blind people."

ZE:A's Hyungsik shared how happy he was to star in his first movie.  "I was also drawn to the film's main purpose and even asked advice to the visually impaired patients.  I found out the patients experience different symptoms.  For example, one person we met conversed with us while making eye contact."

Onto playing a blind person in the melodramatic film, Han Ji Min described, "It was hard to act it out in the beginning...The one thing I regret was not being able to fully express myself since usually we would look each other in the eye when acting.  However that wasn't the case this time, so I felt my gestures weren't as pronounced."
