Girls' Generation's friendship continues to make you go "awww" as they support each other despite their busy individual schedules.

Last night, YoonA posted two shots of her with Seohyun, revealing that she had gone to watch the maknae's musical, 'Mamma Mia,' even meeting up with her backstage for the pictures.  She wrote in the comment that Seohyun did well, which is of course what every fan would expect from the hardworking maknae!

YoonA also wrote, "There were so many classics that I got choked up."  Don't they look cute?
