I don't even know what their arc is about lol, I skip over them everytime
Me too their love triangle is dull and annoying. If he likes one over the other he can say it and even if he likes both he needs it say it so it can be done and over with.
It's not like a love triangle. Goblins need yang energy through sex which blue haired guy ( Geumsun) gets through sex with the reaper (704). Geumsun quite likes 704 as I see. And 704 agreed to sex in return of Geumsun helping San. Cause 704 thinks it's his mistake for what happened to San in the past that ain't disclosed yet. I don't see any love triangle. If u r talking about the Yama guy I think his intention is more on Geumsun than on 704. Yama did some things just to piss Geumsun off cause as I told u 704 is special for Geumsun. This is their story. And it's quite interesting unlike u say.
I see it though so it's my opinion
I might be the only one but the blue hair dude and the other reaper that blue hair dude has sex with. Idk why they annoy me but they do !
