The whole webtoon is drawn using a mixture of East Asian painting formats with a modern take. Some parts include watercolour for the minor details and shading. I'd suggest you check out East Asian art, it's gorgeous :)
I didn't think to call this art style watercolor until the panels where the ghost bride recalled her name (the part where the art transitions into the negative space (the canvas texture, which I also just noticed a few weeks ago) in paint splotches. Like that part looks to me like watercolor paint effects but I can't really say the same for the rest because it looks crisp and the colors aren't transparent. Is it safe to call this semi-watercolor?
