Girl group AOA have left their comments after topping several music charts immediately after releasing their new song 'Heart Attack'.
On June 22, AOA held a showcase for their third mini album 'Heart Attack' at AX-KOREA in Seoul.
During the showcase, AOA revealed their thoughts on their new song topping several music charts, stating, "We don't realize what happened yet. We are so thankful that we topped on Chinese music charts even though we haven't event visited China yet."
ChoA said, "As AOA members started to focus on individual activities since 'Like a Cat', we had to prepare this album without having much time. We worked hard to release this album but we were very nervous. Anyway, we ranked number one on music charts so I guess we could do it well on music shows."
Meanwhile, AOA released 'Heart Attack' on June 22.
