No, they aren't ^^
We Got Married [WGM for short] is an MBC TV show on Saturdays that just pair up idols/celebrities together and see how they would be as a married couple. Each week, the couple gets a new mission to accomplish ^^ there are also MCs commenting on everything, and sometimes they switch the screen from the couple to the MCs, and they comment on things - there are guest MCs, and previous ones have included f(x)'s Luna and SNSD's Yuri. Also, the couples are often nick-named with a couple name. For example, Seohyun + Yonghwa are named the "Sweet Potato Couple" for Seohyun's love of sweet potatoes, and also called "YongSeo Couple", which is their names combined.
Previous missions have included things like going on a couple trip, making a song together, and more. There have been about three seasons, I think, and in the first season there were about four or five couples: Crown J and Seo In Young, Alex and Shinae, Jung Hyungdon and Saori, and Andy and Solbi [who were my faves!]. Then in the second season, some of the couples remained, and then the show went onto a new angle, by adding a real-life couple. It wasn't really popular, so they changed it back to the old style, and now they have Khuntoria and more ^^
