AOA’s Choa features in the first video teaser for AOA’s impending comeback in June with their third mini album “Heart Attack.”

In the short 25 second clip, Choa may very well give you a heart attack as she seduces the camera. There is no music playing in the video, just the sound of an electrocardiogram that goes haywire then flatlines, surely not unlike the progression of fans’ hearts as they watch on.

AOA also recently uploaded onto their Facebook two teaser images featuring lacrosse sticks grouped in a circle on a field and the members’ legs in sneakers and striped socks. The caption reads, “LEAGUE OF AOA,” alluding to a possible sports motif for their comeback.

Meanwhile, anticipation for AOA’s comeback is at an all time high as they are slated to go head-to-head against girl group SISTAR in comeback showcases. “Heart Attack” will drop online and offline on June 22, the same date as AOA’s comeback showcase.
