Seohyun is next in line for the teasers for Girls' Generation's upcoming 'Holiday Night' album.

The 34-second footage features the idol singer dancing the night away dressed in glamorous attire, as she looks back on her decade long performance with the famous group. "I truly feel that the youngest is loved the most. That is the pride of Girls' Generation, they told me. I happen to be the youngest out of all the members. I feel like I am making a huge impact on Girls' Generation. Although our expressions may be different, we all have the same heart. They will always be on my side forever. I'm glad to have been born a Girls' Generation member."
