Rookie vocal group Rush has made their debut today.

This group is a vocal group and is a part of Oscar Entertainment, which also houses Bobby Kim, Double K and more.

Their debut song is a medium tempo dance song that talks about a woman's feelings after a break up.

The three members are all the same age of 25 and have worked as vocal trainers and chorus singers for famous artists before making their debut.

They will be making their first debut performance tomorrow on Mnet.
