Hey! I checked out the "raws" you sent me. Because this is an original Korean manhwa, the link you posted actually goes to a site that hosts manga/manhwa/comics scanlated into Chinese—not the actual Korean raws. However, in the Chinese scans, it's 李世浩 which would be pingying-ified into Li ShiHao. It's like the Chinese pronunciation of Lee Seho (Both languages put surnames in front), with "Se" = "Shi", "Ho" = "Hao", and "Lee" = "Li", so I'm 95% sure it's "Lee". I couldn't really find a correlation between the English and Chinese for other characters like Carvel and Mano though. O.o
I haven't read too far ahead, but I think Seho will definitely be an obstacle for Mano and Carvel to overcome. Seho is pretty obviously a Vampire Hunter, with a history with Mano. I'm predicting that Seho was traumatized by vampires in the past, thus the reason for his desire to "clean them up". In my eyes he's leaning towards the "bad guy" side, because 1. He tricked and used Mano to get info on the vampires that are his friends. 2. He's a vampire hunter... 3. He will most likely make Mano choose a side (Humans or Vampires) 4. MANO AND CARVEL BELONG TOGETHER HE'S MAKING IT MORE COMPLICATED
What I'm going to tell is not really important. But I just want to share that I noticed chapter 10 and chapter 11 have different names for Seho. So what really is it? Haha.
