you guys the author didnt die, there was this whole scandal with the publishing company that got sued bc they were pirating some mangas/manhwas. Since they got sued a lot of authors and artists left them (the artist for this left the company)
Aw sad times
Honestly I read this on a whim but I cant wait for another chapter it looks like it'll be really sweet. Hopefully she responds to his confession soon tho, I like it when mangas show the actual relationship too
