Stitching on neck and eye color I got nothing for but the blacked out parts looks like it's covering a former tattoo, gotta make sure Guwon doesn't remember his past.
You’re thinking of Corrosive. Dif story where Won was born half zombie (with the red and blue eyes). We don’t know about Guwon, yet.
Between the pale eyes, stitching on neck and black like decaying arms, is he immortal like those undead but a bit more special. Wasn't he born that way if I'm not mistaken his mom turned while pregnant in a flashback. Been a while so might be getting it mixed up with another story that's similar.
