Married At First Sight season 18 headed back to Chicago and introduced Karla Juarez, AKA Karla J, a professional hairstylist ready to start a family, and there’s more to her life than meets the eye. Married At First Sight experts paired her with Juan Franco, who felt the experiment was perfect for him since women didn’t consider him a marriage material due to his looks. Besides introducing the Chicago-based couples, Married At First Sight season 18 also reunited the MAFS experts, Pastor Cal Roberson, Dr. Pia Holec, and Dr. Pepper Schwartz, to provide the couples with advice and support.
