HyunA and Hyunseung already got fans buzzing about their impending return as Trouble Maker with their first risque teaser photo, but get ready for more as they will be revealing a new teaser every hour for 7 hours today (26th KST) and tomorrow (27th KST)!

The duo have launched their official site, and from now until around 4 PM KST today, they'll be updating the site with a new hint every hour about their return with second mini album 'Chemistry' and title track "There Is No Tomorrow" on the 28th.
