In 2006 she announced she would join the Hip-Hop Dance group Roo'ra, although she withdrew in 2007 before releasing any new material. The announcement was made at the same time as Roo'ra's announcement of their comeback with a 'best of' album, hence she is credited on the album although she didn't participate on it.
In 2009 she joined the group MADmoiselle, which released one digital single before disbanding.
Nine years after her debut, in 2010, she made her comeback as a solo artist, under the stage name Rottyful Sky, with the release of the digital single "No Way (Rottyful Sky song)". At that time, she became the first singer to be produced by actor-singer Ryu Si-won. On June 24, 2010, Sony MUSIC launch the first Korean video of "No way" in 3D. On February 12, 2013, she released a second digital single "Get Away".
