We Got Married.

We got freaking married. 
That show gave people mixed feelings.
It was cringe worthy and giggle inducing and it made the viewers cover their eyes better than an horror movie.
In other words they loved it.

And by they I mean 'Milady'. 
Five girls under CUBE Ent.: young, fresh and laid back. A rookie group debuted in early 2018.
People were expecting a strong and y vibe, like 4Minute or an upbeat and colorful title track like CLC's Pepe.
They were a little taken a back when they saw and heard a slow, melodic song with flowing gowns straight from the 1910's (The leader loved it most, it made her think back when she was younger and she listened for hours to Steps' It's The Way You Make Me Feel).
It was new and unexpected and soothing and in little time very very loved.

Later the same year they became elegant and mysterious ladies with feathers and glittery dress and lyrics that made you wanna swing. Fitzgerald would have been proud of them. On an interview and when asked by the company itself, they all stated they would have been more than honored to participate on the show.

They were working on the 3rd mini album, when their manager was first contacted by the show. She wasn't supposed to tell them anything for the time being ("This way the reaction would seem more spontaneous" they said).
They were trying and testing different angles, concepts and maybe scripting it less and simply let people be more them and less celebrities. The new PD seemed to think it was the best way to save the show.
Four new couples, for the Anniversary Special, starting mid-April. Introducing them little by little, each first episode an hour long. It was supposed to work.

In the end it did work.
It worked perfectly (and sometimes not just for the ones who participated in the show...)
