These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: King Of Hell
Foe Yay: Between Murin and Majeh, though mostly on Murin's side. He tends to get in Majeh's face, he's really eager to meet him again, is almost obsessive when it comes to Majeh and the first time they are in the same room together he calls Majeh "friend".
Nightmare Fuel: Could be called Body Horror the Manhwa with all the demons, monsters, gross distortions of bodies, rotting living corpses and horrible deaths within.
