No it's an original series written and illustrated by the same artist, so no novel! I'd say, you can read up til the end of the second season then stop to let it marinate. Although the story is stellar, the author tends to take A LOT of time on flashbacks and fleshing out secondary characters, so following it weekly can be unsatisfactory. Do yourself a favour and read the first two seasons tho, they will be the best thing you've ever read on this platform:))

does this have a novel? and if yes, are we close to the ending yet? i've been marinating this after reading some chapters and i'm having a FOMO so bad, but i tend to lose interest when i read ongoing stories when im done catching up up to the latest chapters so :<
