Girl group Girls' Generation watch a music video from 5 years ago and express their thoughts.

Girls' Generation gathered together to watch and reminisce a music video that they shot 5 years ago.

As they watched their "Into the New World" music video, the members commented and remembered their thoughts and feelings from back then.

The members commented that they practiced one year for this music video as they spent one day for one part of the choreography.

All the members also squealed as their youngest member Seohyun showed up on the screen. Her young and innocent image was still seen as she performed in the video.

They also commented that they wore almost no makeup in this video and was told to smile at all times.

Member Hyoyeon commented that this was one of the only music videos that they remember filming each part of. Other music videos that they filmed were all filmed when they were busy so they did no remember much on filming it.

Girls' Generation reminisced on how much they have grown within 5 years, both physically and mentally.

Girls' Generation will be coming out with their 6th Japan single, Flower Power, on November 14.
