Koo Hye-sun, one of South Korea's top actresses, is enjoying a surge in popularity in Taiwan as a hallyu (Korean wave) star thanks to her starring role in the KBS-TV drama ''Boys Over Flowers,'' which closed in March.

YG Entertainment, Koo's agency, said Friday that Koo is being wooed in Taiwan to appear in dramas and music videos.

Even before ''Boys Over Flowers,'' Koo won fame in Taiwan as she starred in hit dramas such as ''The King and I'' and ''Pure in Heart.''

Koo received a warm welcome from Taiwanese fans during her visit last month.
