Manhwa

South Koreans love their manhwa (만화, 漫畵). While Japanese adult manga had a strong influence on porn manhwa, there are many differences in the visual style, stories, and cultural elements.
Chinese porn manhua is almost a copy of adult manhwa.
With adult webtoons (웹툰), manhwa18 became famous worldwide with help of the Internet. One of the best-known places for webtoons is Toomics.
