Girl group EXID's new single is set for release on Wednesday.

With the return of lead singer Sol-ji, who was taking a break due to health issues after developing hyperthyroidism, it is their first album in two years getting together all five members.

"I'm sorry that I have kept my fans waiting for so long. I worked hard on this new single to make it up to them," Sol-ji said.

With a teaser clip unveiled ahead of the release, the girls are getting ready to hold a showcase in Seoul on Wednesday to promote the single.
