With AOA’s comeback just a few days away, they have finally revealed their music video teaser for “Heart Attack.”

Continuing on with their sporty lacrosse concept, we also see the beginning of a school story line featuring Seolhyun as the new transfer student.

From the 30 seconds we get to hear, it sounds like they are going for a more upbeat dance track instead of their popular sexy style.

AOA will release their third mini album, also titled “Heart Attack,” on June 22. They will also be holding a showcase that day for their comeback.

Listen to their album highlight medley on page 2.
