i found the novel on https://nyxscans.com/series/my-possession-became-a-ghost-story-novel and https://anubisscans.com/novel/i-possessed-someone-and-turned-into-an-urban-legend/. nyx scans (in my opinion) has better quality translations, with free chapters up to 45, but anubis scans has free chapters up to 108. where did you find the novel?
to be honest it's been more or less an year since i read it, so i'm not entirely sure if it was really in this website but it seems like it was on "buntls" as they have about as many chapters as i read. also, thanks for the links! i will reread it from the start :D
this novel is so nice but i could only find the first 70 something chapters TT excited for the manhwa tho
