H:GH TENSION was the first group to debut under dream chaser ent in 2012. the hype around their debut died out rather quickly and the group has been in a constant struggle ever since. constant concept changes and a few controversies caused by ill-mannered behavior of some of the members led to a rather bad reputation and they were left with nothing but to leave for japan for a while. 
The group enjoys a lot more attention since one of their members made it into the top 11 of produce 101 season 2.

Deja-Vu debuted in 2014 and remained a nugu idol group until 2015. they finally gained recognition through various variety shows and multiple appearances on immortal song where they managed to win south korean citizens with their strong vocal skills. honestly, talent is what is carrying this group, even though their bubbly personalities are well-loved by fans around the world.
They are currently one of the most famous groups in k-pop and the reason dream chaser ent did not go bankrupt yet. unfortunately, each of the members has a dark secret.

mighty F is supposed to live up to deja-vu's fame with a rather fierce and unique concept. the group was originally planned to debut shortly after the unfortunate media bomb was dropped on dream chaser entertainment.
Little is known to the public about the group, but rumors are going around, claiming they don'T get along with each other and most of their labelmates.
nobody knows if they are just unlucky victims of finger-pointing to distract from the actual culprit.
So far, the debut of the group has been postponed to an unknown date.

while everyone is pointing at the idols, nobody suspects the ones in charge of the groups to be at fault. there are three managers who have to deal with the groups on a daily basis, living in the dormitories with them. each of them tries to make the most out of their group and it is known that H:IGH TENSIONS' manager, in particular, feels that their group is treated unfairly, while deja-vu's manager is fighting off any kind of accusations of favoritism. Mighty f's manager in the meantime struggles more in keeping the rookies in check.
