Vocal group 2AM revealed a unique teaser.

On the 7th they posted on their webpage a video named 'Her Story' which captures 4 different love stories of women.

In the video are Lena Park, model Han Hye Jin, Universal Ballet Team Kang Yeh Na, and actress Park So Yeon. With the theme of '1 1/2 years since break up' the four women honestly talk about their past loves.

In the video Park So Yeon gives a rather cold interview, saying "how do you live if you remember your love story from a year and a half ago?", while Lena Park commented "the times with him gave me a lot of inspiration".

This trailer catches a lot of attention because their song 'You are like me' is playing quietly in the background.

If the women in the video are sharing their love story, Jo Kwon's voice expresses the heart that cannot say he's  not ok when he isn't.
