I think 19 and 20 are a completely different manhwa, I was confused too and the was like..."is this Mondays Savior"? What? Lamster
I think it happened to another manwah I was reading - especially the recent updating (but old) ones - and the sad part is you can’t find anywhere else at least not beyond the amount of chapters that is already in other manga sites (translated) - can’t be helped
18 and 19 are the same
Thank you for pointing this out. I was just reading it and I thought to myself that I've read this before. Then I saw your comment. It's fixed now.
Thank you for informing that it is fixed - good luck with rest of your projects
