Just like any other trend, the trend of K-pop idol unit groups are coming to a close.

Many of the idol members that were in unit groups are now slowly making their way to their original groups to prepare for their comebacks.

The first of these groups is INFINITE. The group will be coming back on March 21 and hold a 'D-Day' promotion as well for their new song, "Man in Love." They have been releasing individual teasers and posters every day up until their release date.

Super Junior, who has also been busy with unit groups, dramas and musicals, will be coming back together to begin their 'SUPERSHOW5' tour.

The group will also be visiting South America this time as well.

4minute's unit group, 2Yoon has also joined the group again to make way for their comeback as well.

On the other hand, there are some idol groups that are bringing out a unit group for the first time. One group would be ZE:A. They have created a 5 member group called ZE:A-FIVE and have debuted in Japan.
