In 2010, the singer released two singles; "Nagging" alongside Lim Seul-ong and "Good Day", which both peaked atop the Gaon Digital Chart and became two of the best-selling singles in South Korea, accumulating more than 4 million total sales.

Her second studio album Last Fantasy was released in November 2011 and was supported through the single "You & I". The album and the single debuted atop the South Korean charts with the album selling around 125,000 units and the single more than 6 million paid digital downloads, making it the second best-selling song in South Korea.
