So it is a webtoon on the Line website (the Japanese version). Usually this means it is an original story, but that is not allways the case. The "Wrath and the Dawn" is an adaptation of a popular book series. Still when I searched the title in diffrent languages only information on the "manga" came up. {Manga is in quotations because webtoons are a specaluzed sub set designed to be read while scrolling. Webtoons usually have single shot panells while true manga has multiple boxes per page. Google tends to lump them together though so I guess this little rant is just for me then }
