"Fuufu Koukan" is a Japanese term that roughly translates to "Marriage Partners" or "Exchange of Marriage". The manhwa, also known as a webtoon or digital comic, revolves around the lives of couples and explores themes of love, relationships, and marriage. The term "Raw" typically indicates that the content is untranslated, directly from the source, and often implies that the manhwa is being shared online without official translation or distribution.
