I forgot the name (as usual), but the main guy is blode with red eyes if I remember correctly. He's like mentoring the prince who's like a sociopath or a psychopath and that prince fell for him and locked him up. The main guy is like a teacher? A eunuch? I honestly forgot as well, but he was barred from doing those things because the dudebro prince wants him for himself
Okay I'm back again after a while... Its about this broke ass guy breaking in a shaman's home and breaking this crystal ball that heightens his yin/yang energy or like that ball encases the curse of the goblins. and this handsome red haired man that is the leader of the goblins takes him from those who abducted him in the first place in the human world. Last I read it he escaped thru a painting and I forgot the title
It’s Dreaming of the Dokkaibe

It's unfortunately not this! The pearl was from an old dude shaman, not the main protags' grandma (atleast from what I remember from dreaming of he dokkaebi), and he got kidnapped by the goblin people when he broke it. It released some pink ass smoke and yea... Goblins tried to r him but this head honcho hot ass masked goblin guy stepped in and got him. Well, he's the guy that r'd him(?) and there's a "scent" on the main guy that attracts the goblins toward him. Main guy was locked in place for safekeeping because apparently fucking people with the right energy cleanses the big shot goblin's soul or something. And this protag has an overwhelming amount of it, whereas most humans die once they get f'd but he didn't so
Sorry it’s this
