That's strange I though it is a manhwa?

I think you meant manhua but I think the author may be in Taiwan?

I thought Korean manga are called manhwa. Am I wrong?

yes korean manga are manhwa, chinese are manhua. hence this is a manhua

Yes I kinda get that, it's just the art style make me think it's a manhwa from the beginning. But when I see the censored I know it's manhua cus in manhwa they don't censored it. That's why I was confused.
