It might be a bit confusing at first cuz vol 4 ch 1 is chapter 33 in manhwa, so you can just skim the begining a lil bit until you find the part where hajung got back from digging his friend grave. Cuz that part in the novel is a bit different from the manhwa. Idk if they decided to expand the scene in the next season or skipped it.
