Looking for this horror manhwa I read a long time ago (around 2010), not sure if it was a manga or a manhwa but the characters' names are Korean. If I remember correctly it was about two long-haired young men (one is not human I think) solving mysteries and encountering ghosts/demons. It was a series but I only got to read one volume so I don't have many clues (>_<). Does anyone know this manhwa or anything close to it?

Horror Collector, maybe?

Or, with a completely different tone but a similar premise, Banhonsa?

Hmm.. not exactly what I'm looking for but thanks for replying! 🙂

I don't think this is it, but it might be S.I.D
