I mean for manhwas masters are a big deal, usually they're the same as getting a parent and the bond between master and disciple are treated as such. Personally i believe a master's presence is long overdue, however, usually after a strong person is forced to start from zero due to poison or curse there's usually a wise master-esque presence to help them start over. You know, before we get invested in the status quo. I kind of get why the golden dragon parts were rushed since a lot of people just want to see dark back in action again.
