Akuhyou Fusai no Irekawari

Erna is seen as a "fallen priestess" with a bad reputation. However, in reality, she is a true saint who can miraculously heal people's ailments, an ability that her adoptive father has exploited and forced her to use secretly for his own gain. When she suddenly loses her powers after enduring his abuse and is no longer of use to him, she is married off to Sigrus, a margrave feared as the "clergy killer." Unable to bear the harassment and loneliness in her new home, one night she weeps under the moon, exclaiming, "I just want a place where I belong." When she wakes up, she finds herself in Sigrus's body! Through their swapped bodies, they discover each other's hidden true feelings for the first time, and a deep, awkward love blossoms. The hearts of the two, once frozen, are now filled with a sweet passion as they are drawn to each other. Original Webtoon Official English
