Idols who failed to impress the audience after their debut are given another chance to be back on stage in The Unit. Korean top producers will give them a chance to shine in a brand new unit with new members, concepts and content. (Contestants credited here are sorted by final rankings.)

Somebody is like a dating show with an interesting twist; the contestants are all dancers. They are from various styles of dance: ballet, street dance, Korea traditional, etc. Their mission is to try to meet a right partner for both art and love. Each of them has a unique personality and different reason to find love. But they are dancers; they know how to convey emotion through movement of the body. Observing the complex 'Ssom(flings)' between them, the show will make us appreciate some addictive stories of romance.
