Girl group Girls' Generation (SNSD)'s Tiffany proved herself to be a 'manner girl.'

Recently in an online community forum, several pictures were posted under 'Tiffany covering Sunny's naked face, so cute.'

The revealed pictures were of Tiffany and Sunny leaving for Japan yesterday for their arena concert. Tiffany covered Sunny's naked face with her passport.

Internet users who saw this commented, "Tiffany is so cute," "Tiffany has manners," "Sunny looks tired," "This is good to see," and "SNSD naked faces are still so pretty."

SNSD will be holding '2013 Girls' Generation Arena Tour' until the 21st.
