After announcing their comeback with their fourth single "Girl's Day Party #4" yesterday, the ladies have returned with new concept photos for their title track, "Don't Let Your Eyes Wander"! Their title track was produced by composer Nam Gi Sang, who created the girls' double home-run with "Twinkle Twinkle" and "Hug Me Once".  With sweet lyrics about a girl asking her boyfriend to look at no other girl but her, the song is full of cute aegyo unique to Girl's Day style. The song has a special story of its own, as it was composed when Nam was hospitalized for fatigue. Despite his condition, he was determined to keep his promise to Girl's Day, proving their strong teamwork and friendship. Their single will contain a total of two tracks, including a remix of the title track. Check out their new photos below! [gallery link="file"]
