Get your minds out of the gutter, folks. We're only talking about the friendship between these two female idols. Kara's sexy and bubbly personality Nicole has recently introduced her mother to the world via the program KAIST. What several people are not aware of is that Nicole's mother owns a ramen shop around KangNam. So what's so special about this ramen store? Well, the members of SNSD have dropped by this place quite a few times in the past. Their autographs, along with several other celebrities', were seen around the store by those eagle-eyed netizens. The two representative girl groups debuted around the same time and often competed with one another during similar promotional periods. However, instead of deepening their rivalry throughout the years, the members of Kara and SNSD have deepened their friendship with one another. It helps that they're all around the same age, hmm? Fans of both groups have even christened them the "SoKa Line" (So Nyeo Shi Dae and Kara Line). Earlier in 2008, fans also included the Wonder Girls to this girl group line and called the power trio "WonSoKa Line." SNSD has been focused on individual and group activities as of late and the members of Kara have just enjoyed a nice vacation from their fast-paced promotional period for their last album Revolution and are to return some time this month.
