On the January 14 broadcast of the Watcha-original music variety program 'Double Trouble', the contestants put on duet stages based on the theme of 1990's or 2000's hits!
For this second main competition round, the contestants had a chance to switch their duet partners around, with the exception of ChoA and WEi's Kim Dong Han, who remained on the same team.
First, ChoA and Kim Dong Han delivered a moving stage to H.O.T's "Hope", joined by a children's choir.
Next, 2AM's Seulong and Weeekly's Monday performed a seductive rendition of Ivy's "Sonata of Temptation".
SF9's Inseong and Minzy, on the other hand, paired up for a brilliant tango performance to "Must Have Love" by SG Wannabe and Brown Eyed Girls.
Another new duet pair this week, Jang Hyun Seung and KARD's Jiwoo put a groovy new twist on Rain's "Rainism".
Finally, Hyolyn and Block B's Taeil came together for a refreshing vocal performance this week by singing Davichi's "8282" (Video above).
This week, the stages voted by viewers as the most memorable were by Inseong and Minzy, and Seulong and Monday! Look forward to even more new duet pairings and exciting stages on 'Double Trouble', airing every Friday nights at 6 PM KST via Watcha!
