So there's this manhwa i read... Where the ml and fl where married but they absolutely hated each other so one day they swap bodies accidentally such that the ml was in the fls body and the fl was iñ the mls body... This way they got to experience each others problems... The fl got to experience the stress of leading a kingdom as the ml was an emperor and the ml got to experience the stress of dealing with the bullying of noblewomen the fl had to endure. Anyone remember?
