Yeaaa lol im confused on their relationship too?
Just to add.. At the start of the story, 704 (reaper who works for Yama) was suspicious about the circumstances surrounding Eunjae’s case. While investigating he discovered that despite not liking each other, Yama (king of the underworld)+Geumsun (goblin) were secretly working together to stop Hwan.
It's been hinted that 704 and Geumsun might have some history but up until recently, their relationship has been purely transactional. 704 gives Geumsun the yang energy (+reaper blood) he needs, and in exchange Geumsun shares some of it with San.
Geumsun+Yama mark 704 for different reasons: Geumsun does it in order to remove Yama’s scent, and bc his own scent previously acted as a deterrent for Hwan. Like Syxx said, Yama pretty much does it to provoke Geumsun…he tells 704 that when he marks him, it makes Geumsun furious.
After the confrontation with Hwan (when San used the bow and arrow to shoot him), Geumsun visited Yama who told him to return 704. Geumsun was reluctant, but knew that staying with Yama in the underworld meant that 704 would be safe from Hwan.
can someone explain the whole situation with 704 yama and the other dude??? like a recap or something and like their relationships too and stuff bc my brain can not comprehend shit and it’s honestly preventing me from enjoying it as much as i used to
