South Korean girl group AOA topped various music charts across China and Taiwan with "Heart Attack."

On June 23, the day after the release of "Heart Attack," AOA topped China's music download site Kuwo, and on June 25, they topped China's biggest music site Kugou's Korea-Japan chart. Their music video also has been holding onto its top-ranking status on YinYueTai's V chart.

AOA's popularity reached over the borders of China to Taiwan. "Heart Attack" topped Taiwan's popular music site O Music's K-pop download chart, and their other tracks "Really Really," "One  Thing," "Come to Me," and "Luv Me" also took all the chart's spots in the top 6. AOA previously kept their no. 1 status for over 2 months in 2014 with "Like a Cat" and "Miniskirt," and the group became the most popular K-pop girl group in Taiwan.

Many foreign music sites and media are keeping their eyes on AOA's comeback as well. On June 24, Billboard praised AOA by stating, "From Catwoman-esque spies in 'Like a Cat' to lacrosse players in their new single, AOA confirm their position as the K-pop act with the best taste in costumes with the girl group's latest release."

In the midst of the group's growing popularity, AOA will show off their lovely charms through MBC Show! Music Core on June 27 and SBS Inkigayo on June 28.
