A recap of Married at First Sight Season 15 premiere View this post on Instagram Instagram PostLast week, viewers met the Season 15 couples and saw them prepare for D-Day after sharing the happy news of their marriage with their loved ones.A contestant named Miguel entered the show wearing a Dungeons & Dragons costume. He told viewers that comic books were an escape from reality for him. His match Lindy, however, was introduced as a regular church-goer and a Seventh Day Adventist, whose religious beliefs often affected her personal life.Meanwhile, another contestant, Binh, confessed to his friends that he was very frugal and did not buy material possessions. He said he would rather invest every bit of his money in crypto. He apparently never used the AC even when it was very hot and ate peanut butter sandwiches and bananas every day for breakfast. The new season features five couples from San Diego: Lindy and Miguel; Alexis and Justin; Krysten and Mitch; Morgan and Binh; and Stacia and Nate. Only time will tell if these couples are a perfect match.Married at First Sight airs every Wednesday on Lifetime at 8 pm ET.
