A photo collection of�Girls' Generation's "daily facial expression changes"�has become a hot topic online.

The photo shows Girls' Generation and a related facial expression for the members, each day of the week. On Monday and Tuesday, the members look tired, but as the week moves on, they start to look a little more cheery. Friday and Saturday, they are smiling brightly. One thing that netizens noticed was that�maknae Seohyun stays consistent, smiling throughout the entire week.

The collection definitely reflects the difference between what most people feel when the week starts and when the weekend begins.
